I think it is a bit better on the K10D but have not used it enough to be sure. >So, my question to the happy owners of Pentax D FA Macro 100 F/2.8: >Do you observe any of these two issues or it was a bad apple (aka >lemon)? No, seems to be typical for this lens, allthough there might be some sample variation. That said, whenever I use a macro with a tripod, I use manual focusing anyway (or use the A* 200mm :-) For bug-hunting the AF is nice though ...
