Nikon D4s Review

The Nikon D4S is an impressive machine in many ways. Having the D800 as my everyday camera, I can say that most of what the D4s does well the D800 also does fairly well. But there are some standout differences. The most obvious is the speed of the D4s. Shooting at 11 frames per second is something of a revelation when you’re used to the D800 clunking along at just 4 frames per second. Thank goodness we’re not burning through film at that rate.

Another interesting difference was that I altered my attitude toward ISO with the D4s. Partly because I felt more confident in the results I would get and partly because I wanted to push its capabilities, I was pretty relaxed about letting the ISO climb up to heights I would not dream of going to with the D800. And the results, within reason, were impressive. I had Auto-ISO maximum ISO set to 12800. On the D800, I don’t like to go above 1600. The D4s sensor is not a magic wand and the high ISO shots need help in post with noise reduction, but the results at 12800 and 25600 can be surprisingly good and 6400 looks great. Dynamic range should and does, based on online research, degrade linearly at high ISOs for both the D4s and the D800 at 1 stop of DR lost for each 1 stop increase in ISO. This makes me think that perhaps I should be pushing the D800 higher to see how closely I can match the D4s results. I normally use little to no noise reduction and I think there may be some unexplored potential in the D800 at high ISO settings.

The D4s blazes away at 11 frames per second, with every frame in-focus and perfectly exposed as your subject moves around. The D4s' speed is much more than just its 11 frames-per-second specification; it's all the other things like its metering and auto white balance and face-recognition autofocus and focal-length tracking Auto-ISO systems that all work twice as hard and fast as other cameras to keep those ten-point-five frames per second all looking great. I worry about getting there and pointing the camera in the right direction, and as I preset my D4s, it takes care of the rest.

The D4s just shoots and shoots and shoots. It's unstoppable. It grabs ultra-high ISOs automatically as needed if it gets darker without anyone having to stop and set anything (I set my ISO at AUTO ISO, focal-length based auto-control of slowest shutter speed set one click faster than usual for sports).

The D4s feels great; its sculpted body fits a man's hands far better than the plasticy D800, whose grip is just too tiny for comfort.

The D4s' viewfinder is years ahead of consumer cameras like the D800 and Canon 5D Mark III; the D4s uses magic auto-dimming LEDs to show the AF areas without covering anything, just like the Canon EOS 3 of 1998, while the D800 and Canon 5D Mark III use black LCD AF area indicators that cover the subject. Sadly the D4S still lacks the mind-control AF point selection of the EOS 3.

The D4s of course has a built-in vertical grip with two total shutter releases (each with its own separately programmable function button), two sets of command dials, two AF-ON buttons, and two new Canon-inspired thumb controllers.
