The novelty looks almost identical to the flagship two years ago. However, by the standards of top-end cameras two years, so the present restyling, which brought more internal changes than external, can even be called early. The key difference is that the processor Expeed 4, which according to the manufacturer, allows to reduce the processing time by 30% and in theory should affect the AF speed in LiveView. Also, the camera now supports recording Full HD videos in modes 50p/60p. In addition was expanded and the wide range of sensitivities up to 409600 pixels, which allows you to shoot the moon at night with it, but at the cost of high noise. In addition, there appeared the possibility of recording in RAW resolution 2464h1640 points.

The package

The delegation of the Nikon the past couple of years hold sacred rules of the company, and never give up on testing or pre-sales samples, therefore, almost always fall on the camera testing simultaneously with the beginning of local sales, and always in complete set. And D4s in this regard is no exception. D4s unlike neoretro camera Df is only available in version “Body”, that is to say “carcass” without a lens. So, in addition to the box of the camera includes the following: protective cap BF-1B Shoe cover for accessories BS-2, Li-ion battery EN-EL18a with protective cover, battery charger MH-26a with power cable and two protective covers for the contacts, clip USB cable, clip HDMI cable, cover UF-2 connector for cable with a stereo mini plug cable, USB cable UC-E15, CD-ViewNX 2 CD, strap AN-DC11.

Appearance and usability

Of course, the first thing you notice when using the flagship Nikon cameras is the “square” case with duplicated for convenience in portrait mode controls, impressive size, and a very considerable weight. Although here it is worth noting that the main, though not entirely a direct competitor, the Canon EOS-1D X in terms of weight and dimensions is actually no different. In addition, a large mass has its advantages, especially in professional applications — solid weight acts as a stabilizer. However, to hold the camera quite comfortably in both landscape and portrait mode thanks to its ergonomic handle and solid rubber lugs under the big toe on the back surface of the housing.


The design of the case, as D4, are widely used magnesium alloys. Body panels of the camera are exactly the same as its predecessor, so if you close in the name of the last symbol, then the predecessor immediately will be difficult to distinguish even for experienced user. The difference is only one — is the surface of the control stick, which is now covered with a small notch, making them easy to work even with wet fingers. By the way, D4s is one of the few cameras of Nikon, which is still going on the Japanese company’s factory. In modern conditions the automation seems to be not so important, because now any gadgets collect no worse than in Malaysia, China and Thailand, but still warms the soul.

Front is a lens mount, two front control dial, microphone, connectors synchronization cable and remote control/GPS unit, concealed split rubber plugs, and a couple of programmable keys. The rear body littered with various controls. Here is just two displays — the main large and colored, as well as duplicating a monochrome segment display. Given the fact that the most frequently changed settings can be adjusted using a combination of hot keys and dials, extra segment display is used even more frequently primary. Above the main display are buttons delete and move to the view mode and viewfinder. To the left of the display buttons display the main menu, lock/help/selecting the color mode, a pair of keys to zoom, enter, and change display modes main display.

Under the display you can find additional keys to select a level of sensitivity, quality, white balance and activation recording a voice tag. Slightly to the right of the secondary display is the key transition mode LiveView, surrounded by the selector lever display mode (photo/video). In the right part of the rear side of the case with 8-way navigation key, complemented by pressing input on the center, the lever lock selection of focus areas, system speaker, and a pair of rear control dials, pressing “AF-ON” and joysticks.

Most of the keys, save both the “AF-ON”, equipped with uniform white backlight, which is absolutely not distracting in good light, and most importantly does not blind with the camera where it is most needed — in the dark. In the case of D4 we had observations to cover the illuminated keys, which is quite fast flew, but fortunately, such a peccadillo for novelty has not been noticed. Also the right side is the door compartments memory cards, and extended the castle.


Top center mounted hot Shoe. In the left part in the schematic ring combined key select the metering mode, flash mode and bracketing. Just below this group of keys includes a dial to select drive mode. The right side is a segment display and selection key setting mode expobar, the introduction of exposure compensation, video recording and shutter release button surrounded by a lever power, the extreme position which activates the backlight both segment display and buttons at the back of the camera. The bottom is just a connector mounting on a tripod.


The left side of the camera is pretty much loaded. There are 4 plugs installed connectors, wireless modules, USB cable, microphone and headphone ports, HDMI and Ethernet. In addition, on the left side mounted pushbutton operating mode selection/area selection AF, surrounded by a lever to switch between automatic and manual focusing, as well as the battery is equipped with dual lock. To the right is a soft key and duplicating the shutter key surrounded by a retainer.
