I recently systematically tested the AF accuracy of all my Pentax AF lenses on my K-S2 body, and realized that they all need some extent of microadjustment. My FA 31 required +10, FA 43 required +9, SMC-F 24-50/4 required +8 (which yielded fair accuracy on all FLs, but not superb), and Takumar-F 70-210/4-5.6 required +5 (the same story as the SMC-F 24-50/4). I remember that the FA 35/2 which I sold after purchasing the FA 31 also required something like +6. Does this indicate that there might be something going on with my K-S2?
Sincerely
Sounds familiar
I had to adjust for Tamron 28-75, Pentax FA 50mm 1.4, DFA 70-200, Sigma 180mm Macro. Zoom lens needed different offset for different focal length. To make it worse i did this for K1 and K3. It took two weekends. I noted down the results so that whole exercise does not go waste. But decided to use AF only when I have to. Fortunately both my cameras have Focus peaking, and this is satisfying my needs. My challenge was switching over from view-finder and Live view. Additionally if I have to shoot using AF at F2.8, I plan to back it up with f4.0 shot.
