I will like to try and describe the Miss Focusing problem on my D7000 with the 4 pictures in the Memory card (please read by computer), took by D7000 with N24-70mm, F2.8 and N50mm, F1.4. The pictures were took on a tripod about 3 meters away from the object, in an environment of five 2700K OSRAM energy efficient light bulbs.
As you can see in these pictures, there is an obvious difference in focus accuracy between the pictures took by focusing with Live view (AF-F Norm) and the ones took by AF-S single point focus. (Even with Flash (SB-900), AF-S still cannot focus correctly).
Under the environment mentioned above, almost all pictures took by AF-S with a large aperture are miss focused (mostly back focus). And this miss focus problem also happens very often when I shoot out doors. This has been a big trouble to me. Please help me solve this problem! Thank You Very Much!!

3/8 為了確認Nikon清楚瞭解相機問題所在,我又寫了這封信去說明:
Dear Mr. XXX
Thank you for your letter. I am more then willing to pay the Estimate Fee you require.
However, before you send it back I will really like to make sure that the problem on my camera is solved. I am worried because sometimes when I use AF-S to focus on a subject over 3 meters away (but the subject fills the focus point), the camera often chooses to focus on something else, like the back ground or some other object. This seems to be more than just a problem of "Difference in AF accuracy between AF-S lens and Live View" and "Inaccurate focus". (I am sorry if I didn't describe the problem clear enough when I sent the Camera.)
Therefore, could you be so kind to explain a little more about what is wrong with my camera and how you plan to fix it. If possible, it will also be nice if you can provide some test photos took by my camera when testing. Thank You Very Much!! Best regards, John F AAA (Can reply in Japanese!)
