Hello guys, recently I bought a DA* 16-50 and yesterday I found out that some pictures shot at 50mm f/2.8 were out of focus.
Today I made some test with a couple of objects and it results that my K20D + 16-50 is affected by front focus.
I tried to calibrate it, and here is the result:
(focus on the middle battery, crop 100%)
+0:
+10:
My best result is when the calibration is set to +10. I would like to increase this value in order to improve the autofocus tuning. Is it possible in some way?
Regards,
Andrea
