Web Cam. SmartCam HD1080p quality camera is supported in LAN and WiFi, and easy to operate via a web browser or via mobile phone. This cam also be accessed via the android application which can be downloaded at Google Playstore or with an iPhone application. Additionally as a security camera, IP camera made by Samsung is also applicable to two-way communication using a mobile phone user. For example, users of office and home users are aware of theft, it is only by using the user's mobile phone, users can scare the thief by using the microphone of the mobile phone. If the build-in speaker quality is less, the user can add speakers via the 3.5mm jack. With two-way technology of the IP camera, users are also able to listen to the sound captured by the camera's IP.

One more excellent feature is the direct night mode function automatically when dark or night. In addition, motion detection of the IP camera is fairly sophisticated, where able to distinguish between the movement of the leaves with the movement of pets and humans. There is also a micro sd slot to store the record of motion detection so that for users who do not constantly monitor his IP cameras can see from the records that have been stored in the micro sd.

By 1080 HD lens used and the wide lense used increasingly adding positive value of this product, when tested these products and placed in a corner or center of the room, the IP camera is capable of displaying almost the entire contents of the room very well. The ability of the lens to show better with delay look pretty quickly. The ability to detect motion only in certain places are also present in this product, so let users simply want to monitor the movement only at the door or window or aisle, it can be done. So the movement apart spots or areas that have been determined to be ignored.

Tips to choose good domain for your blog
domain
For you are an online business or a professional blogger, has a website with a unique domain is something that you want as it becomes your identity and your site. Many online discussion that talks about how to choose a good domain for a site. But wait, what the actual definition of the domain? Below is a definition of the domain according to wikipedia:

Domain is given a unique name to identify the name of the server computer as a web server or email server on a computer network or the Internet. Domain function is to facilitate the users on the internet at the time of access to the server, this is also used to remember the name easier of the server that visited without having to know a complicated series of numbers known as IP addresses. This domain name is also known as an integral part of a website such as for example "wikipedia.org". The domain name is sometimes also referred to as the URL, or web address.

Here are some tips on choosing a good domain for your site:

1. Choose a domain name that corresponds to your name or your business.
When you create a website / blog for promotional purposes or sell products / services - such as selling perfume and it would be better if you choose a domain name that is associated with the perfume. Example, for example to create a website / blog for promotion or selling perfume, then you should choose a domain: perfumeshit.com | saleperfumeoriginal.com | perfumeoriginalcheap.com | and others. We recommend that you do keyword research before choosing a domain name, keep your domain containing the keywords of your business, have quite a lot in the search engines, and competition is the key word is not too difficult. Use the help of Google Adwords: Keyword Tools to help you find the keywords that are suitable for your domain name.

When you create a website / personal blog, then you should use your name or nickname you as a domain, for example Ihavenomoney.com.

2. Choose a domain name that is easy to remember 
Use a simple domain spoken, understood, and remembered. When you tell someone you verbally domain name - for example, by phone - a domain that is too long or difficult to understand would be difficult to remember or even be able to confuse others.

3. Just use the TLD (Top Level Domain) ending in dot com for your domain name. 
TLD is .com domain exetension most memorable person. For example, when there is a domain with the same word - for example perfume - usually people will try to open the extension dot com website first. To check the availability of a domain name, you can use this site www.domainsbot.com assistance.

4. Never use a domain name such Racist or PORN or Serial killer or NAZI style
Because it will give a bad impact on your website and of course your own image. Search engines like google usually oriented keywords, if your domain name contains words that are redistributed, this can result in your site blacklisted by the search engines, which ultimately will have an impact on the number of visitors to your site.

5. If possible, avoid the addition of words or characters that do not need to be on your domain. 
For example, the use of hyphens, numbers, space, blank or additional letters - this may affect the power of SEO a website. But if it should be forced to add character to a domain, then you should use the minus sign (-).

6. Do not buy a domain name that has become a trademark.
For example: amazon.com, facebook.com, google.com. Do not even think of buying a domain that is similar to that domain because it is likely that you will be sued by the company owner of the trademark.

7. Buy domain only of the Registrant are reliable at an affordable price.
One of the domain registrant that I often use is Namecheap.com, in addition to low cost facilities are also very profitable. Namecheap domain standard offer price of about $ 9.98 per domain per year - will be even cheaper if you have a coupon discount. In addition, they also provide the facility with free whois guard (only in the first year), while the other registrant will normally be charged.

After reading this article, hopefully you can find a domain that matches with a blog or website that you will wake up. If there is input and questions please send us your comments! Sorry for my Bad English.. Dont curse me please!

Getting started with the Fujifilm GFX 50R
Getting started with the Fujifilm GFX 50R

A really lightweight case! In a detailed press presentation, we were able to quickly take over a copy of the Fujifilm GFX 50R. Our model is not fully functional and does not even have the final coating at its hatches. This did not prevent us from appreciating the ergonomics and especially the lightness.

It's a long tradition at the Japanese manufacturer. Since 1948 with the release of Fujica Six, the brand is present in the medium-format sector with devices designed for reporting. It is the specific form of these products that inspired Fujifilm for its GFX 50R: its offset viewfinder on the left gives it the look of telemetry cameras. It must be said that Fujifilm has made this neo-vintage look a real hallmark since the launch of its hybrid X-mount range. Although it is equipped with a medium-format sensor, it is more X-Pro 2 only to a GFX 50S that makes us think the device. But it should not be forgotten that the GFX 50R remains bulky.

Slightly longer than its average-format senior, the camera remains imposing with a footprint similar to that of a film-based reporting device such as a Mamiya 7 for example. Nevertheless, note the efforts made by Fujifilm to refine the case that measures only 66.4 mm thick. Above all, it's the weight of the device that impressed us with only 775g on the scale. Equipped with a fixed focal length as the 63 mm that we see in the photo, the set is really light and perfectly suitable for travel.

This is the main objective of Fujifilm: to get the medium-format system out of studios to make it portable. The brand has for this purpose provided seals at different strategic points of the housing.

If it has an off-center viewfinder, the GFX 50R unfortunately does not have a hybrid optical / electronic vision as the X-Pro 2. A problem of space according to Fuji, but also feedback from users who would be so used to the electronic view that they would neglect the optical sight we were told. Still, we have high expectations around this viewfinder equipped with an Oled panel of 3.69 Mpts and that our first contact is not very positive. The magnification is less important than on the GFX 50S and the display lacks fluidity. We will need a definitive model to judge. But it is true that since we have been watching the excellent viewfinder of the X-T3, we have become very demanding!

Although it does not have a marked handle, the GFX 50R is very easy to handle and is pleasant to handle. On top, the two adjustment knobs are easily accessible. Locking the speed setting prevents unintentional manipulation, while exposure correction is set far enough to stay in place. On the back of the camera there is an adjustable thumb wheel, shortcut buttons to different functions and especially a joystick that we appreciate so much to quickly change the AF point. That of the GFX 50R works only in contrast and it will be necessary to wait for the output of GFX 100 million pixelsto enjoy a hybrid system. Our first tests still showed good responsiveness.

In the back still, the screen is oriented only horizontally. No doubt a choice related to the size that avoids the disgraceful outgrowth of the GFX 50S. From this screen, we can navigate menus that Fujifilm has unfortunately not changed. On the other hand, good surprise, the menu Q is compatible with the tactile features of the screen. As on the X-T3, we can easily change the fingertip a lot of settings.

Before having a functional box to carry out more in-depth tests, let's end this overview with connections. The GFX 50R has a microphone jack on its left shoulder, next to the viewfinder. Under the device, there is a USB-C port and a power outlet located opposite to the hatch under which the battery is housed, identical to that of the GFX 50S. Finally, on the right side of the device, two hatches provide access to the mini-HDMI port and the dual slot for SD cards. Like all the latest Fujifilm cameras, GFX 50R has a low power Bluetooth connection. On the other hand, unlike the GFX 50S, it does not have a headphone jack.

Some questions to Makoto Oishi
On the sidelines of the presentation of the new devices, we were able to ask some questions to some Japanese officials including Makoto Oishi, development manager for the GXF 50R. 

Following the presentation of the X-T3, we were all waiting for an X-Pro3. Is the GFX 50R the new successor of side-view cameras?

Makoto Oishi: No, absolutely not. You know, a lot of people have asked us, an X-Pro3. At Fujifilm, there are two separate ranges with APS-C format and medium format. The new GFX 50R belongs to this family and if I can not tell you if there will be an X-Pro3, the medium-format does not replace this one.

With the X-Pro3 which is the only "range finder" model, you have used a hybrid vision system that is both optical and electronic. Why not use this system with the GFX 50R?

Makoto Oishi: It's true that this hybrid system is a lot of fun, but it was difficult for us to integrate this system in the GFX 50R because we changed a lot of elements inside and especially the battery which is now under the viewfinder. A hybrid view involves an optical system that is quite complex to implement, and in particular for a medium format package. The set was too big to fit into the case. 

Why not integrate, as on your next GFX 100 model, a mechanical stabilization system and a phase-correlated autofocus on the sensor?

Makoto Oishi: Ah ... Yes, we would have liked. For the electronic stabilization system, we did not have the system at the time and it takes up a lot of space and for us compactness was a priority. For autofocus, the current sensor just does not allow it and could not offer a phase correlation system on this case.

For video recording you stay on a fairly (too) conventional format in H.264 / H.265 which is not necessarily very easy to work and edit. Why not propose recording in ProRes format for example?

Makoto Oishi: That would be interesting, but it does involve a lot of calculation and currently I do not think we can do it with the current processors.

Kraken Tournament Edition: The new version of the flagship Razer helmet
Kraken Tournament Edition: the new version of the flagship Razer helmet

Razer Kraken Tournament Edition. USB sound card and THX Spatial audio, launched at 99€! The Razer has unveiled yet another iteration of its flagship helmet: the Kraken Tournament Edition. This edition Tournament benefits, among others, a USB sound card, the new THX Spatial Audio and more features than the analog versions.

The Kraken Tournament Edition is essentially based on the Kraken Pro V2, adopting the same characteristic design and materials. The helmet philosophy is based on an aluminum frame (hoop + hinges) and the hoop is covered by a double leatherette / woven fabric cover. The only change is in the atria: the area in contact with the user's head is now covered with a soft cloth instead of imitation leather, which would ensure better heat dissipation. The gel "refreshing" and the small channel adapted to the branches of glasses are still relevant on this model.

Kraken Tournament Edition: the new version of the flagship Razer helmet

The big news is the presence of a USB sound card that gives access to more features and control possibilities. Of particular note is the arrival of THX Spatial Audio, the brand's new virtual spatialization technology (owned since the end of 2016 by Razer) and certainly related to the THX Positional Audio Solution . In theory, this technology would give access to several modes: extended stereo, 5.1 and 7.1 surround, and even what Razer calls a "spatial sound"that is, future compatibility with object-oriented formats. What's more, this THX Spatial Audio technology would affect the quality of communications (voice clarity, sensitivity, noise reduction, etc.). It goes without saying that we will not fail to check this out during the full Kraken Pro Tournament Edition test.

Kraken Tournament Edition: the new version of the flagship Razer helmet

As often, the sound card also serves as a remote control. It has two buttons for listening volume control, a button to activate / deactivate the microphone, a potentiometer to manage the balance between the sound of the game and the cat, another to control the low frequencies, and a last button to enable / disable the THX Spatial Audio function. Here is the very complete technical information shared by Razer on its website. 

Headphones:
  • Frequency response: 12 Hz-28 kHz. 
  • Impedance: 32 Ω at 1 kHz. 
  • Sensitivity (@ 1 kHz): 109. 
  • Input power: 30 mW (max). 
  • Loudspeakers: 50 mm with neodymium magnets. 
  • Inside diameter of the headset: 56 mm / 2.2 inches. 


Microphone:
  • Frequency response: 100 Hz-10 kHz.
  • Impedance: 32 Ω at 1 kHz. 
  • Signal-to-noise ratio:> 60 dB. 
  • Sensitivity (@ 1 kHz): -45 dB ± 3 dB. 
  • Capture mode: unidirectional ECM microphone. 

The Razer Kraken Pro Tournament Edition is already available for 99.99 €. It is available in two colors: green and black.
Nvidia GeForce RTX 2080 Ti: The game in 4K at 60 fps finally become reality
Nvidia GeForce RTX 2080 Ti: The game in 4K at 60 fps finally become reality

Nvidia GeForce RTX 2080 Ti Review. Raytracing in the line of sight! The GeForce RTX 2080 Ti award. Twenty-seven months. This is the exceptional lifespan of Nvidia's GeForce GTX 10 graphics card series. Excellent at launch and still offering excellent performance in games, they are now replaced by the GeForce RTX 20. Obviously announced as faster than the previous ones, these new models bring with them the ability to accelerate the hybrid rendering for ever more realistic games. The GeForce RTX 2080 Ti is the spearhead of this new line and is positioned as the ideal solution to play in 4K at more than 60 frames per second.

Nvidia GeForce RTX 2080 Ti CHARACTERISTICS:
  • Chip: TU102
  • GPU frequency: 1350 MHz
  • Memory: 11 GB
  • GDDR6 memory
  • Memory frequency: 1750 MHz
  • Double height: Heatsink
  • 3x DisplayPort 1.4 outputs; 1x HDMI 2.0b; VirtualLink
  • Driver tested: 411.51

PRESENTATION
The GeForce RTX 2080 Ti and GeForce RTX 2080 are the first Nvidia graphics cards to offer hardware acceleration of raytracing.
The GeForce RTX 2080 Ti and GeForce RTX 2080 are the first Nvidia graphics cards to offer hardware acceleration of raytracing.

Like all GeForce RTX 20s, the RTX 2080 Ti uses a "Turing" GPU. We have discussed the subject extensively, broadly and crosswise, in a dedicated article. We will not go back in detail on the novelties brought by this architecture, but to summarize the key points. Turing brings a new method of distribution of computing units, units dedicated to the IA (Tensor Cores), units dedicated to the acceleration of rendering raytracing (RT Cores) as well as an optimization of the different levels of cache.

The GeForce RTX 2080 Ti is based on the use of a TU102 chip consisting of 18.6 billion transistors, but not all calculation blocks are used. Thus, of the 72 SM blocks present, only 68 are active on this model. Each SM has 64 calculation units, 4 texturing units, 6 deep learning units (Tensor) and 1 dedicated raytracing (RT) block. In the end, this gives rise to a chip gathering no less than 4,352 calculation units, 272 units dedicated to textures, 544 Tensor Cores and 68 RT Cores. The whole is accompanied by 88 rendering units. So this is a nice evolution compared to the GeForce GTX 1080 Ti which included for example "only" 3,584 calculation units as shown in the table below.

On the other hand, the operating frequency does not change much on paper. It must be said that the transition from a 16 nm etching process to a 12 nm FFN process (Nvidia specific TSMC FinFET) is not a big change. Indeed, contrary to what may suggest the change of nomenclature, the 12 nm is more to see as an optimization of the 16 nm process. Therefore, the expected gain on power consumption will not be as marked as when switching from 28 nm to 16 nm.

The base frequency is thus announced at 1350 MHz, against 1480 MHz on the 1080 Ti - a regression therefore on the minimum frequency held by the new chip. On the other hand, the average GPU Boost frequency is increasing since it goes from 1 582 MHz to 1 635 MHz on the Founders Edition models (the model tested here). Beware, the Founders Edition are no longer seen as reference models, but as models overclocked factory. Thus, some Nvidia partners will be able to offer non-overclocked variants, whose average GPU Boost frequency will be set at 1 545 MHz, or at a frequency slightly lower than that of the 1080 Ti.

GPU Boost 4.0: a slight evolution for more control
Nvidia has nevertheless revised its frequency adjustment system and passes the GPU Boost in its fourth iteration. With GPU Boost 4.0, it is still a question, as on GPU Boost 3.0, to adjust the operating frequency according to the applied load, a threshold of power consumption and the temperature of the chip. The change is in the temperature management, which has an intermediate temperature threshold before which the frequency passes to its nominal value. According to Nvidia, this would maintain a higher frequency than previously when the cooling system of the graphics card is efficient.

An overclocking simplification tool that evolves only slightly
Evga's Precision X1 will feature the Nvidia Scanner feature to simply overclock your graphics card.
Evga's Precision X1 will feature the Nvidia Scanner feature to simply overclock your graphics card.

Nvidia also decided to let users change the value of the temperature thresholds. No home utility for this, but a third-party utility such as Evga's Precision X1 or MSI's Afterburner, for example. This software can also integrate the Nvidia Scanner kit so as to offer a simplified manual overclocking.

Similar to the automatic overclocking system introduced on the GeForce GTX 10, the Nvidia Scanner still allows utilities to act on the voltage level to define which maximum frequency is the most stable. The new system would nevertheless be more accurate with a more realistic GPU load. The user, for his part, must first set the limit of consumption and temperature - as much put the sliders to their maximum - and play on the temperature thresholds we spoke a little higher. In short, it is automatic in large part, but still not entirely.

The GeForce RTX 2080 Ti and RTX 2080 can operate in pairs, in SLI via an NVLink bridge. What allow to play on an 8K TV, ensures Nvidia.

GDDR6 makes its debut
Nvidia also took the opportunity to inaugurate the GDDR6. On its top-of-the-line 10-series models, the company used GDDR5X and retained classic GDDR5 on mid-range and entry-level models. The GeForce RTX 2080 Ti, RTX 2080 and RTX 2070 for their part are equal weapons at this level and therefore all enjoy this new type of memory that allows both to increase the flow and is energetically more interesting with a gain 20% on energy efficiency. 

On the GeForce RTX 2080 Ti, Nvidia does not change the quantity and so always offers 11 GB of memory and a bus to 352 bits. The changeover to a frequency of 1750 MHz however makes it possible to propose a bandwidth of 616 GB / s, well superior to the 484 GB / s observed on the GTX 1080 Ti and on theRadeon RX Vega 64  - AMD's card uses HBM2, which is much more expensive to produce and especially to integrate.

A neat food stage
Nvidia also assures that it has been paying close attention to the power supply of its card, which displays a thermal envelope of 260 watts (2 x 8-pin PCIe power connectors are present), 10 watts more than the model it replaces. It is thus a question of a stage composed of not less than 13 phases intended for the supply of the GPU and of 3 phases for the graphic memory. It is also about iMON DrMOS systems, able to activate only when it is necessary - fewer units are thus engaged in idle,for example - to optimize energy efficiency. This is typically the type of power stage used on high-end graphics cards from Nvidia's partners. This did not prevent our test model from sending a strident sound ( coilwhine ) at its reels in the menu of some games.

NOISE
The cooling system is new and relies on the use of two fans that cool a radiator that hugs the full width of the board.
The cooling system is new and relies on the use of two fans that cool a radiator that hugs the full width of the board.

With its RTX 20, Nvidia is making a big change in the cooling system. Exit turbine type ventilation found on the models of the brand since GeForce 6 (2004) and place a system based on two axial fans. Once again, the manufacturer is on the side of its partners who, in their high-end versions, use this type of cooler - sometimes with three fans. From experience, we know that this type of system proves less noisy than turbines while offering more efficient cooling. The disadvantage is that some of the generated hot air is forced inside the housing rather than being completely expelled. Proper ventilation of the housing is therefore preferable. Note in passing that the finish of the map is rather admirable, with its gray metal shell with beveled corners. Only the central part, made of plastic, would have won to be more neat.

At the back of the cards, a metal plate helps heat dissipation. The finish of the GeForce RTX 20 is also excellent.
At the back of the cards, a metal plate helps heat dissipation. The finish of the GeForce RTX 20 is also excellent.

In order to offer a convincing system, Nvidia also chose not to use copper heat pipes, but rather a steam chamber plate, applied directly to the GPU and spreading across the entire width of the board. to be in full contact with the finned radiator. A metal plate then makes the connection between the steam chamber and the rest of the components (memory chips, power stages). At the back, the metal plate is not only decorative, unlike the one we usually meet; it serves here as heat sink. Two fans 8.5 cm in diameter cool all.
And it must be admitted that the result is convincing in games where ventilation is particularly discreet, at the edge of the audible one meter of a closed box. The Nvidia system is thus much quieter than any of the partner brand systems (Asus, Zotac, Gigabyte, MSI) taking place on the GeForce GTX 1080 and 1080 Ti, to say. On the cooling efficiency side, the system maintains the GPU at its temperature limit of 87 ° C. 

On the other hand, the ventilation remains at almost the same noise level at rest. Blame the fan on top of the feed stage that continues to spin rather quickly off load. A problem that Nvidia hopes to fix with a driver update.

CONSUMPTION
The power supply goes through the use of two PCIe cables: 2x8 pins on RTX 2080 Ti and 8 + 6 pins on RTX 2080.
The power supply goes through the use of two PCIe cables: 2x8 pins on RTX 2080 Ti and 8 + 6 pins on RTX 2080.

As we have seen, switching to 12 nm is a big optimization of the GTX 10 16 nm process rather than a real new process. In games, Nvidia's new card is more energy-consuming - more computing units to power, in particular - than the model it replaces. There are peaks at 296 watts against 260 watts on the 1080 Ti. The average is around 290 watts, which is quite close to what is observed on a Radeon RX Vega 64. Note the 25 watts of power consumption at rest. A particularly high value (we expect between 5 and 10 watts usually) that would be due to a bug, according to Nvidia. The firm said to work on the subject to propose a patch via its driver.


The absolute power consumption analyzed alone does not mean much. It must be correlated with the level of performance achieved in order to appreciate it through a value called energy efficiency. And there, the ratio between the number of frames per second achieved in the games and the power consumption gives the RTX 2080 Ti as slightly better than the GTX 1080 Ti. Not surprisingly, it offers a much better result than AMD's RX Vega 64.

PERFORMANCES IN THE GAMES
In the games, spent several minutes of non-stop testing, the card sees its real GPU frequency oscillate between 1395 and 1470 MHz for an average of 1 455 MHz or about 50 MHz less than the GeForce GTX 1080 Ti.


On our panel of games, the GeForce RTX 2080 Ti is on average 34% faster than the GeForce GTX 1080 Ti when games are run in 4K. The newcomer is also 25% ahead of the Titan Xp, the fastest model Pascal architecture has emerged. In other words, AMD is pale with a Radeon RX Vega 64, which is 79% behind average.




Obviously, the gap is narrowing as the definition goes down. The RTX 2080 Ti thus maintains a lead over the GTX 1080 Ti of 24% in WQHD and 10% in Full HD - the processor, a Core i7-8700K , limiting performance more and more. Compared to the Titan Xp it is about 15% and 5% respectively.

Finally
The slice lights up in green. It is possible to play on brightness and effects via third-party applications like Evga Precision X1

With the GeForce RTX 2080 Ti, Nvidia promises a graphics card capable of delivering more than 60 frames per second in 4K. In practice, it is true that many games can be run at more than 70 fps while the rest is close to the 60. A more than convincing result that we can only salute all the more than the RTX 2080 Ti is, at the time of writing these lines, the only graphics card on the market capable of proposing this. The various improvements brought by the Turing architecture are bearing fruit since we reach an average difference of 25% at best compared to the best Pascal cards, the Titan Xp. However possible that this difference may seem insufficient in the eyes of some players who have waited more than two years between the two generations of cards.

Because the problem for Nvidia is that the firm uses here a particularly large chip and used in most of it. In clearer, Nvidia still has enough to offer a "supermodel" type Titan exploiting all the units of the chip, but the difference with the RTX 2080 Ti can not be huge. And not to be deceived, the arrival of a chip even more massive can be on the program as the GPU used here is already huge. In short, unless you switch to 10 nm, Turing seems to deploy almost all its strength through the GeForce RTX 2080 Ti.

Dual ventilation is both efficient and quiet. Good ventilation of the housing is however necessary.
Dual ventilation is both efficient and quiet. Good ventilation of the housing is however necessary.

Suddenly, the firm is focusing on other areas to sustain this range with the promise of a better rendering thanks to raytracing and, to a lesser extent, the DLSS (a less greedy system than conventional antialiasing). Nvidia goes even further by assuring us that it is the video game industry that is pushing hybrid rendering and not itself, which, for its part, simply wants to offer something to exploit it properly. We summarize the state of these two technologies in our box.

There remains the question of the tariff. Offered at € 1,259, the GeForce RTX 2080 Ti is a particularly expensive graphics card, offered in the tariff segment held by the Titan until then. A high price that Nvidia justifies by the premium aspect of the cooling system and, above all, the size and complexity of the chip used - which we will not contradict. As such, it offers better for cheaper than the Titan Xp. But we will not fail to notice that it is at least 70% more expensive than the GeForce GTX 1080 Ti while offering only 34% additional performance. The raytracing and implementation of units dedicated to deep learning(for the DLSS in particular) are therefore paying a high price, so hope that the promises at this level are completed. The player equipped with a 4K screen will not really have any other alternative, unfortunately.

Hybrid rendering and DLSS: promises for the future
With Turing, Nvidia is not limited to offering a more powerful series than the previous one. The company also relies on two other assets supposed to embellish the games. Starting with the hybrid rendering combining classic rasterization and raytracing. The promise is simple: to offer games with more realistic effects thanks to a hardware acceleration of the part of the rendering realized in raytracing. For now, we have only been able to try a demo made available by Nvidia as well as a draft of the next version of 3DMark in addition to testing a few titles at Gamescom. The nature "beta" or "alpha" of these tests does not allow us to draw a definitive conclusion at this stage, but we will not fail to return to the subject through a dedicated article.

The other idea of ​​Nvidia is the DLSS, its new system to reduce aliasing in games. As discussed in our article on Turing architecture, this system is less resource-intensive than conventional antialiasing systems while offering the same rendering quality. Once again, we have not been able, at the time of this writing, to thoroughly test this new system on real games. The DLSS will take part in dozens of games over the coming weeks. We will also come back to this in a dedicated article.

Finally, Nvidia has also reviewed a part of its "engine" to manage the rendering type HDR. Failing in some cases on the GeForce GTX 10, it would be more effective here - understand that the activation of the HDR will have very little impact on performance. Nvidia thus picks up AMD at this level. Due to lack of time, we were unable to carry out comprehensive tests on the subject. Same story: we will come back soon.


STRONG POINTS:

  • Game in 4K at 60 fps finally now possible.
  • Energetic efficiency.
  • Silence of operation.
  • The promise of hybrid rendering.
  • VirtualLink output.
  • Quality of manufacture.

WEAK POINTS:

  • Ventilation does not shut off at rest.
  • Still little visibility on raytracing performance.

CONCLUSION:
Nvidia delivers here a graphic card perfectly adapted to play in 4K at 60 frames per second or more. A first that is saluted especially as the firm brazenly distance the best of the rival cards, the Radeon RX Vega 64. The firm also aims for rendering better quality via raytracing and spared no efforts to achieve by achieving a particularly complex chip, expensive to produce, which is not without consequences on the price of the card. The hybrid rendering, although pushed by the industry according to Nvidia, remains a very good promise on which it will still be necessary to be both cautious and patient since the first games bringing this support are not expected before mid-October 2018 earlier.

Presentation and first grip! Presenting today its 24 mm f / 1.4 GM, Sony brings to eight the number of objectives of its G Master professional range. Above all, the brand unveils an optics with two XA lenses and a new DDSSM autofocus motor. We were able to use this new lens for half a day. Here is our first opinion.

445 g and a maximum diameter of 75.4 mm: the first observation that we make taking into account the Sony FE 24 mm f / 1.4 GM is its very reasonable weight compared to the competition. The Sigma 24mm f / 1.4 DG HSM Art, which we tested in Canon mount, weighs 665g and measures 85 x 90.2mm, the Canon EF 24mm f / 1.4L II USM sports 650g for 83, 5 x 86.9 mm, and the Nikkor AF-S 24 mm f / 1.4G ED displays 620 g and 83 x 88.5 mm. This relief is significant on the ground, especially as the lens that has a FE mount is associated with devices themselves lighter, such as the A7R III that we used for our tests.

High-end construction
The Sony FE 24 mm f / 1.4 GM is the eighth optical G Master range and the thirtieth E-mount lens of the brand to cover the 24x36. It joins the 24-70 mm f / 4 GM, 70-200 mm f / 2.8 OSS GM, 85 mm f / 1.4 GM, 100 mm f / 2.8 STF OSS GM, 100-400 mm f / 4.5-5.6 GM OSS, 16-35mm f / 2.8 GM, as well as the very recent 400mm f / 2.8 OSS GM in the category of outstanding lenses served by an innovative optical design.

Made from 13 elements divided into 10 groups, the FE 24 mm f / 1.4 GM integrates 3 elements ED glass for the treatment of chromatic aberrations and, especially, 2 lenses XA (eXtreme Aspherical) in charge of eradicating the Sagittal flare and offer consistent quality in the center and on the edges of the image. Integrated for the first time in 2016 in the 70-200 mm f / 2.8 OSS GM and 24-70 mm f / 4 GM, these lenses are here for the first time two in number.

The lens also benefits from a surface treatment of Nano AR lenses that avoids the appearance of flare and ghost images due to internal parasitic reflections.

The front lens also benefits from a fluorine-based coating that makes cleaning easier and prevents fingerprints, dust and water stains. The lens is also protected against the insertion of dust and water marks.

Optical quality
Sony says and offer a very high resolution compatible with the very high definition of sensors. We will have to measure the objective in the lab to judge, but our first observations show indeed a strong separating power from the very opening.

Its large aperture f / 1.4, but also its circular diaphragm 11 slices can achieve beautiful bokehs, precisely detaching the planes of the image while providing a velvety blur. The minimum focusing distance of the lens is also one of its strengths since it goes down to 24 cm. We are far from the macro report with a magnification of 0.17x, but we can get close to its subject and integrate it into its environment.

The vignetting is visible at full aperture, but is easily corrected with editing software and disappears quickly when closing the diaphragm.

Silent autofocus
Inside the lens, Sony has integrated a new Direct Drive SSM autofocus micro-motor, which has a mark that indicates it has thrust three times that of the previous generation. It is difficult to verify this value, but we must recognize that the objective has been extremely responsive and, above all, perfectly silent. The internal focus, it, ensures a constant congestion, whatever the distance of development.

Ergonomics
In addition to its small footprint, the Sony FE 24 mm f / 1.4 GM is distinguished by its pleasant grip. Sony has equipped it with a diaphragm adjustment ring placed on the side of the frame, which we particularly liked to handle during our tests.

Above all, the brand has equipped the lens with a Click on / off selector that allows you to have a notch of the ring or to enjoy a continuous adjustment of the diaphragm. She thought of videographers who can thus operate in a completely silent way to modify the opening or the focus. The focus ring is wider and comfortable to handle. On the other hand, the goal does not have a distance scale.

On the other side of the barrel, we find a selector to quickly switch between manual focus and autofocus, as well as a shortcut key. This can be customized to maintain focus at a fixed distance or to call different functions selected from the camera.
