This might be off-topic now but the second part of the "What PENTAX Values Most in Future Cameras" video series has been released.

I wrote a brief summary of the video contents.

The result is poor precision and significant incidence of missed focus despite the proper calibration.
I haven't touched the focussing screen because Pentax doesn't support user calibration (for the k-5 you could get shims in the past), but I find that when I focus using the screen (which is really only practical with longer focal lengths or close focus) my images are consistently front focussed.

Canon (and Minolta) had to change lens mounts as they were not compatible with the future; ie AF and electric transfer of data. Canon tried with the FD mount but had to place the electrical contacts on the outside of the mount and lens barrel. It also had a very small diametre making it difficult to make fast lenses with high optical quality (and totally impossible to make fast lenses for todays standards).
No such issues with the EF mount.[COLOR="Silver"]
Minolta continued to support the MD mount right up until Kyocera bought them though. Granted new development stopped, but repairs along with the X370, X700 and all the lenses and accessories that were available in the mid 1980s were available until the old company was shuttered with the merger in 2003.
Contrast this with Canon which was pretty much done with the FD mount by 1990, all support vanished in some markets, though limited support was available in others. No new cameras available, the lens line dropped entirely, and repairs ended.

Why don't you send it in and get it calibrated?
