I got exactly the same results for my test too....Apparently there is backfocussing.....

But my 3 other AF D lenses are fine...including the 50mm


:dunno:

What is the queue like....? How many days did you have to wait.....?

Those who calibrated their D70s.....do you know how the procedure is done......do they use software to do it....

Or they do physical adjustments to the camera......

(worried....dont know if they will leave fingerprints on the mirror...etc...if they actually touch the insides.... :sweat: )

the 2 pics looks alright to me.
dof in front of the focus area is always less than back of the focus area. as long as the selected focus area is correctly focused, IMO that's not backfocusing.

From what i'm reading on the net, I kinda get the impression that backfocusing is not limited to close (1-5m) distances. Apparently, you may have perfect focusing at closer distances, but focusing at infinity sometimes may not be as sharp as it is supposed to be, due to misaligned CCD, or what not. Therefore, tests with the test chart may not be able to identify all backocus problems? Would anyone who has technical knowledge of the ways dSLRs focus be able to clarify whether this is plausible? Or maybe because at longer distances, more likely to be camera shake, user error, wrong fstop etc etc???
