Un essai d'accessoires sur un modèle de présérie

http://www.dslrnewsshooter.com/2012/02/29/notes-on-the-nikon-d800/

My first impression was that the camera body is very well built, similar to the D700 but with a more rounded appearance. The grip was very comfortable in my hands, Keith has much bigger hands than me but too commented how nice it was to hold.

The only D4 video feature I found missing from the D800 is the the 2.7x 1080P crop mode. The D800 only has full frame (FX) and 1.5x (DX) crop options. 

Audio is the same as the D4 with manual control in 20 steps and a headphone jack.
On the preproduction D800 and D4 cameras we also found it was impossible to change the audio level once recording.

We tried both the SmallHD DP6 and Zacuto EVF fed via HDMI from the D800 and they worked as they should without the need for firmware mods – good news. 

Looking at the image on the DP6 it seemed very clean and crisp, even at 1-1 pixel mode. Noise was well controlled.There was moire evident on the monitor though and I assume that Nikon are using line skipping techniques to generate the video output (the current Canon DSLRs suffer from similar moire). Remember that this was a pre-production camera and the final unit may be different. I could not make a fair assessment of sharpness and colour as we were in a poorly lit room with no broadcast monitor.

One other thing that we checked was how well the Zacuto Z-Finder works with the D800. The screen is a little bigger than the previous models and I thought it might not cover. I held the Z-finder to the back of the camera and it seemed fine.

 

Autofocus is not something I recommend for DSLR video shooting, however we did try it on the D800 in video mode. It seems quite quick compared to my 5D mkII but not as fast as newer mirrorless cameras like the Sony NEX7. The focus seems to hunt a little back and forth a lot of the time before settling on the subject.

The D800 is certainly a step up in operability from other DSLRs, if you are a Nikon user already shooting video on a D7000 or D3s then it should be a very welcome upgrade (as long as the image quality is as expected). But with the rumour mill going nuts about the Canon 5D mkII’s possible replacement, I think it will be worth waiting to decide which way to jump if you are in the market for a new DSLR.
