D700 focus challenges


Seems that my photos are generally lacking a tack sharp quality to them since purchasing the D700 about 8 months ago. This could also be a perception issue, so I\'m seeking your assistance and suggestions.

After recently attempting to use the lens align to calibrate the lenses, it became difficult acquire tack sharp focus, even when using a tripod and remote trigger. Here are a few images from the calibration attempt with a 50mm 1.4g prime and a 24-70mm @50mm:

d700 - 50mm 1.4g - @6ft dist. - 1/30s - f/2.8






d700 - 50mm 1.4g prime - @3.5ft dist. - 1/40s - f/2.8 - ISO 200






d700 - 50mm 1.4g prime - @6ft dist. - 1/30s - f/2.8 - ISO 200






Here are a couple of handheld shots, one where the focus turned out decent, and another shot where I expected the focus to be much better @5.6.

d700 -left eye - 24-70mm @66mm - 1/320s - f/4 - iso200






d700 - 4 \'dots\' to upper left of head - 24-70mm @70mm 1/250s f/5.6 - ISO 200






All photos were shot in .NEF 14 bit lossless, and converted to jpg using CNX2. Also of note is that the liveview appears to give slightly better impression of sharp focus, but when zoomed in with liveview, the pixelation is pretty nasty. (Nothing nearly as sharp as the lens align videos.)

I\'ve also recently attempted to use an 85mm 1.4af with the D700 with great anticipation, and finding that the images don\'t seem to be tack sharp at any aperature using my D700 (1.4 through f4+).

Maybe I\'m expecting too much sharpness, but any help or thoughts would be appreciated. Not sure if the camera /lens should be sent in for service, or just accept the current results. And the skills for holding the camera could use major improvement (just an amateur looking to improve), but expected the tripod remote trigger shots to be in better focus.
