It has finally arrived. Nikon has presented the latest revision of its professional reference camera, the D4S, which we’ve been talking about for more than three months, and so far, it seems most rumors where true. Like its predecessor, both for its price and performance, it has been designed with professional users in mind.
The fact that Nikon has maintained the D4 name, and added the "S", reveals that this new camera is actually the evolution of its predecessor, so it shares many of the elements of this excellent camera. In any case, the D4S also offers significant improvements worth reviewing in detail. Let’s start by taking a first look at its most important specs.
- 16 megapixel full-frame CMOS sensor
- ISO Sensitivity : 100-25600 (expandable to ISO 409,600 equivalent)
- Completely hermetically sealed metal body
- 11 fps continuous shooting in FX format with continuous AF and AE higher than the D4
- EXPEED 4 image processor
- 51-point autofocus system (same as D4)
- Improved Autofocus new lock , new restriction options and zone mode group
- Video recording D -Movie Full HD up 1.080/60p in FX and DX format
- Gigabit Ethernet Port, Support for the Wireless Transmitter WT -5A for Nikon
- RAW format file size S to achieve higher transfer rate
- Shutter speed: 30s 1/8,000
- Group Area AF allows for more accurate subject tracking with less ‘distraction’
- EL18a Battery ( 2500 mAh / 10.8 V ) provides 3020 shots per charge (CIPA)
Expanded ISO range and EXPEED 4 processor
According to Nikon, the company’s engineers have listened to the opinion of professional photographers who used the D4 and have decided to modify the camera sensor, which now offers a quick read of the channels and an extended dynamic range. In addition, the D4S offers an ISO range of 100 to 25600, expandable to an equivalent of 409 600, which is twice the maximum value offered by the D4. The sensor resolution has not been altered, and remains at 16.2 megapixels.
The image processor the D4S features, as expected, is the EXPEED 4, which we have seen, for example, in the D5300. Camera designers say this chip contributes decisively to the increase in the ISO performance we just mentioned, improving the ability of this camera to take pictures with little noise in very low light scenarios.
11 FPS and a new AF mode
Another aspect in which the D4S has managed to outdo its predecessor is the maximum shutter speed with autofocus, who has gone from 10 to 11 FPS. It is also possible to generate RAW files with less weight, S-sized, and the transferring speed has also been improved, a process that can be performed using the Gigabit Ethernet connection.
Furthermore, Nikon engineers have also given more features and tweaks to the autofocus system. They have improved blocking, extended the "storage orientation” and increased restriction of the AF mode, but have also added an autofocus mode. The latter is designed to more precisely control the size of the focus area, and thus allow a more effective monitoring and shooting of fast-moving objects.
Video Recording on the D4S
The D4 performs well when recording video, but the D4S incorporates some improvements that, in theory, greatly enhance its capabilities in this regard. It can record D-Movie videos at 50 and 60p, as well as the ability to modify the sensitivity and enable the maximum ISO value in M-mode. It is also possible to choose the cropping format, control the diaphragm motor and manipulate the shutter speed.
Another important feature is that the D4S’ noise reduction system, which according to Nikon minimizes the noise when a high sensitivity value is recorded. We will check this out once we can test it. Sound recording has also been improved. Now users have more control options and can choose the audio range, which, among other advantages, should offer no issues even when strong wind is blowing in a microphone.
Nikon D4S, price and availability
Nikon has said nothing about the official price or release date, but it seems it might hit the market on March 6, at least in some countries, and it will likely cost around 6500 USD, not that much expensive than the D4.
