Hello all.
I have recently bought a D7000, and have not been satisfied with it's sharpness from day 1. I have run around 800 images off so far, and all the lenses I have require various amounts of fine tune, normally around -10 to -14 to get near to a "good image".
I was convinced it was my technique, or settings, or any number of things, but now I am thinking it is the camera. My "best" lens, a pro bit of glass, the 80-200mm f2.8 fares no better, even on a tripod.
So today I took my Nikon 12-24mm f4 lens out for a test.
I have had this lens for a while and have some stellar images shot with it on my D70, so I know it's a good lens, especially around f8.
For the test, I didn't use a chart, or lens align, instead I took it to a local park, and set it on my tripod, aperture priority, f8, 125th sec, and used remote mirror up, 2 sec delay, then shoot.
As a reference, I shot first in live view, which focusses in a different way, here are the images from the live view.
All shots are resized in LR3, with no sharpening, and saved for web.
