Glitches and Details

This page captures various oddities that I noticed so far.

Dial functions — skipping

Both front and rear dials for selecting aperture and shutter speed can “skip”: twiddling the dials three clicks to go from f/4 to f/5.6 might result in f/5 instead. This behavior developed over time, and seems to be slowly worsening. It’s very annoying because one has to verify exposure, rather than relying on click-click-click to go up or down one aperture or shutter speed. And some users report that the problem gets much worse.

As this was reported when the 645D came out nearly a year ago, it seems that Pentax still has not sorted out the mechanical issues.
