The only focus issues I had was with my 85 1.4D and that was corrected with some autofocus fine tuning

On the second two cameras (i.e. the replacements), I did all of the above and then repeated after setting the appropriate AF Fine Tune per lens.

I had a front focusing issue with my old D700 even with the fine-tune option set to max

AF fine tune would NOT solve this issue

I'm sending the camera back to be fine tuned

This actually gave me hope that I would be able to correct the problem with the focus fine tune adjustment setting

year."I did EVERYTHING I could to get my camera fixed and when Nikon experts fail at repairing it... they will simply tell you that it meets "their standards"If front focusing +15 or more than 20 on ALL lenses meets their standards (after fine tuning the left focus is blurry again btw

~-2 AF fine tune

AF Fine Tune, in some cases, seemed to reduce the problem.

AF fine tune would NOT solve this issue

At 24mm F2.8:Left AF sensor with no AF fine tune just started to show blur, it requires -3 AF fine tune(FT) to be in best focus,and requires -1 AF FT to reduce blur to indiscernible level

I did have to apply a very mild focus fine tune to the 24-70 2.8 to achieve optimal results at both the center and the left but that is to be expected

Again find center and left point requires no fine tune

AF fine tune

, I fine tuned my D7000 this way.

and -3 fine tune is totally acceptable, and without fine tune the image quality is acceptable too

D800 has rather fine tuned and greatly improved from D700 in every

Instead of comparing with live view focusing, I scanned through the AF fine tunes from +3 to -6.

Also on the last occasion, the fine tune settings shifted requiring optimization recalibration of all my lenses

I also experimented with using autofocus fine tune on individual lenses.

In another review on the D7000, I noted the AF needed fine tuning on that camera
