another week with the D800 and looks like I'm keeping it for good.
The dynamic range on this camera is beyond my expecations. shadows are recoverable to levels which no canon camera I've owened is capable of, and detail on the recovered areas is very very clean. You can also bring highlights from the dead in LR4. This is the first camera I've owned where a single still can effectively serve as a good HDR image by itself. I still need to bracket for extreme scenes and to retain color, but it is maknig me re-think what was possible before from a single image.
getting the most out of the resolution is relatively trivial with good nikon glass. This is after all the same pixel pitch as a 16MP APS-C body, not even 7D territory much less D3200. As with the 5DmkII, good support and technique is needed to maximize the gains.
Video is very detailed as I'd hoped. Much improved over the 5DmkIII waxy soft look on detailed textures. However like the MkIII, the codec just doesnt' deal with motion very well. Foturnately the atomos ninja 2 will be soon part of my rig to address that and I'll be recording from the clean HDMI out. Lastly, the mosaic engineering AA filter seems to address the moire issue (although it isn't anywhere nearly as bad as with the 5DmkII). I may get it just as an insurance piece of gear but nothing I've shot has had moire issues. I admitedly don't shoot a lot near brick walls or large horizontal patterns so YMMV.
I'm 90% sold on it. Just need to test it with more nikon glass. Btw, 14-24 nikkor. OMG. what a lens.
