Re: Paul I should do another try on the AF-calibration before sending it back
In reply to dick eduard, 8 months ago

In the AF calibration test I did, the error appeared to be entirely within the DOF... it was a matter of just estimating the middle of the sharp region. The adjustment I made had a pretty small real-world effect.

...If only someone would make a big prime that was quite long, like equal to a 400 with TC, but slow to keep costs down. Yeah, something like a 560/5.6 -- it could be cheaper than a Sigma 500/4.5, let alone any big L lens! Wouldn't it be great if Pentax made something like that?
