Nikon D4s sensor reviews 2020

introduction

Nikon follows a predictable cycle following the refresh of its top-flight professional camera, and two years after the D4 was announced, the revised model is now finally with us as the Nikon D4s.

 Like the earlier refresh, externally the new model looks very similar to its predecessor, but although there have been some minor changes on the back of the camera, most of the changes occur inside the alloy shell.

Although the sensor is the same 16.2-Mpix type CMOS device as the D4s, perhaps the most significant change is the upgrade of the Exped-3 to the Expediting-Processing Engine.

 4. Not only does it extend the camera's capabilities with respect to the ISO range (now including a new maximum ISO 409,600 extended setting), but it also offers up to 200 frames (JPEG Fine L) and a new 1080 50 / 60p video capture option. Allows for slightly faster continuous-shooting (now 11fps, above 10fps).

Processor improvements also mean that the D4s can raise more from its battery pack, the revised EN-EL18a.

 Nikon D4s sensor reviews

 

 Nikon's D4 boasts 3,020 shots per charge as opposed to 2,600 from the EN-EL18. In addition to the previously reported video frame rates,

 the D4s adds ISO auto control for video capture in manual exposure (with exposure compensation), as well as recording to an external recorder as well as a memory card.

 Live view output can also be viewed while recording uncompressed video via HDMI. Sound recording now has the option to select the frequency range and level.

Nikon has also reduced viewfinder blackout times, improved Air Force on lock-on and enhanced the 51-point AF system with a new group field AF option offering greater control over AF field size Monitors 5 groups of sensors. The camera is available for pre-order for $ 6,499.

Nikon D4s vs Nikon D4: What's New?

Nikon D4s: low light performance

A score of 89 points with DxOMark, the Nikon D4S achieves a very high sensor and comes in 12th overall in our sensor rankings.

It is on par with its predecessor and full-frame Nikon Df and Nikon D3s (now discontinued), but still somewhat behind the Nikon D600 / 610 and D800 models.

 The color sensitivity, or depth of color as its depth exceeds 24.4 bits and is only lagging behind the class for sensor size.

 The dynamic range is also very good at 13.3 EVs, although it is slightly lower than the firm's current range of DSLRs (including the APS-C model).

While this camera is about shooting under the available light, while you can expect that the low light score is excellent, it is still not quite the leader in this category (although it is very close).

The low light capabilities are exceptional, but Nikon Dfs ranks third in this category after Nikon Df, and has discontinued the older, now Nikon D3s.

Nikon D4s vs Nikon D4

The scores are very similar when compared to its predecessor, with the sensor suggesting that it is probably the same.

 At the base sensitivity, the D4S appears only slightly lower in color sensitivity, but is equal to about −1/3 of a stop. However, things have improved in the dynamic range.

The Nikon D4s can boast a +1/2 stop improvement over earlier models, and there is a slight improvement in low-light performance from ISO 2965 to 3074, not that you aren't noticeable in actual word usage.

 While it is a bit disappointing that Nikon is not exiting this sensor in any way, it is important to remember that it is an exceptionally high performance.

Nikon D4s sensor Nikon D4s vs Canon EOS 1Dx:

The most obvious competitor of course is the Canon EOS 1D X, the firm's first high-speed full-frame model aimed at photojournalists and a formidable camera with extremely impressive capability.

 Lets quickly iterate over the specifications of the flagship Canon before we compare the hard data between the two sensors.


The camera replaces both the photojournalist-oriented APS-H size Canon EOS 1D Mk IV and the full-frame 21-Mpix Canon EOS 1Ds Mk III, both with improved high-speed and low-light capacities and fully redesigned AF systems. Offered.

 Like the D4 and D4s, the EOS 1D X has a full-frame CMOS sensor but is a slightly more pixel-count 18-Mpix device and adopts some serious processing power.

This enables the Canon EOS 1D X to shoot continuously at 14fps (12 fps with constant FA) and provide a maximum sensitivity of ISO 51,200 (204,800, extended).

 Also the Canon EOS 1D X21 was the first to introduce the firm's new 61-point AF system with cross type AF sensor,

lens-sensitive with f5.6 aperture (and faster) and a 100,000 pixel RGB metering system, A variant that was to be used in the Canon EOS 5D Mk III.

At the time of its introduction in late 2011, the EOS 1D X was one of the most fully featured HD-DSLRs and remains to this day. Along with offering 1080p at 30/25 and 24fps, it has two compression formats - a lower compression-ALL-I 'option for the highest quality and a more storage-friendly IPB format. The Canon EOS can shoot at 1D X 60fps rate but not the 1080p of D4s in 720p.

In our tests the proprietary 18-Mpix sensor at Canon has been slightly overshadowed by the Nikon D4s in each of our use cases for a 7-point lead in DxOMark sensor scores.

Personally, the Nikon D4s have slightly better color discrimination than the roughly +1/3 stop on Canon and a slight edge in low-light performance, but the main advantage is to turn off the improvement in dynamic range at base ISO Is close to +2.

Nikon D4s sensor The conclusion

However, Nikon has improved a number, and added several video-oriented functions, most of which have been achieved by upgrading the processor.

 Although some minor benefits have been made to reduce shadow noise and extend dynamic range, sensor performance is largely unchanged. The D4s are not to be called compelling anyway, as it is, but anyone who expects significant gains in performance will have to wait for the Nikon D5.
