Ok, I will get a wireless shutter release.
Do you feel that this camera is more easily "shaked" than earlier models?
And what is the best apperture for these tiny pixels? f. 5.6?
Congrats on the D800, you've just gotten an amazing piece of kit!
You will clearly see more easily a given amount of blur, but I have not noticed a trend to generate a larger amount of blur in absolute terms.
Mirror up is recommended on tripod.
As far as optimal aperture goes, usually somewhere between f4 and f6.3 depending on the lens.
