That's what I am afraid of...now everything is working after the update who knows. I find AF fine tuning extremely tedious and borderline impossible with some lenses, especially screwdrive; the focus is not repeatable enough, large shot to shot variance even with tripod and everything. My guess is that there is a lot of backlash in the mechanical drive, either by design or a specific flaw of my copy, or wear & tear. Fine tuning corrects systematic error, if you have stochastic error it's not useful at all. On the K-3 I did manage to improve the consistency of some lenses, namely the 100mm macro with AF fine tuning. On the new camera I have tried but it does not seem to be necessary it just works, out of the box.
