Nikon just posted a technical guide for the D800/D800E here: http://www.nikonusa.com/en_US/o/Y6wrkA9OU_z04IreazIXl_22UII/PDF/D800_TechnicalGuide_En.pdf Strongly suggested reading for D7000 owners also. To get all the resolution out of these cameras they state: - focus accuracy is critical and suggest using live view when possible (no adjustment/alignment issues with live view. - camera shake is must be controlled - tripod/VR/mirror lock up (live view obviates the need for MLU) when possible. - Oh yeah, use our good lenses. The practical limits for resolution is focus precision and camera movement, not pixel density or lens resolution.
