That could be why I have been having "problems" with this specific TC attached to my DA*300/4 ...
Thanks for the hint.
Something to try and see if it will solve the said-problem.

Originally posted by Stavri I was calibrating my lenses this weekend, and noticed that when I attached the pentax da 1.4x Tc to my lenses, all the saved AF micro adjustments would be reset to "0" . I don't know if this is something that's been covered before in the forum, but thought to give you guys a heads up on the issue.
DA* 300 + 1.4x Tc (left "0" adjustment, right "+1" adjustment)
So, let's say (presumption only) I had the DA*300/4 on its own and needed a +1 fine adjustment ... and I saved that "correction".
Then, I attach the HD 1.4X TC to that same lens ... so according to your findings, the required AF adjustment (if any) would be reset to zero, right?
Once I calibrate this combo and save it, would the camera save it as a lens on its own (i.e.: the lens plus TC = "a lens" ) ?
