I am just back from a 3 days family trip during which I had the opportunity to shoot the D810,
In short, I am impressed. I was shooting with the Sigma 35mm f1.4 and Nikon 85mm f1.4. What struck me:
- the colors are clearly richer and better differentiated compared to the D800,
- the auto white balance seems much better,
- the ability to shoot hand held with live and EFC activated increases the ratio of critically focused and tack sharp hand held images,
- operations are very significantly smoother, it feels like a totally different camera. Live view is one aspect, but it is true from pretty much everything I tried (handling, sound,...),
- AF in AF-C mode is much more reliable, especially when using group mode,
- detail is simply amazing, and I didn't have the Otus that is still under repair. It is very clearly sharper than the D800 (non E),
All in all it feels that Nikon could have called this a D900 without over selling the progress.
Cheers,
Bernard
