Well, aside from the 70-200 issue, two prominent and recent issues related to Pentax poor design decisions include:
- the K-30 problem with the 'brow' or forward protrusion of the pentaprism/flash hump (with the Pentax logo on it) over the lens mount (pic related), meaning that some lenses (a few tilt-shift designs, IIRC) could not be mounted properly on the K-30. Hence the very short lifespan of the K-30 design, attractive as it was;
- the current problem with the K-3 II (and to a lesser extent the K-3) where the flash hot shoe sits very low and tight against the upwards-sloping K-3 II pentaprism hump, preventing some third-party flashes (eg some Yongnuo's) from mounting properly on the K-3II hotshoe.
Luckily, the last problem seems to have been fixed in the K-1 (pic related), where the flash hotshoe has now been elevated a bit and has more room in front of it.
Many of these issues could have been picked up before production began if there had been a test program that subjected the cameras to the very varied user environments that are part of the real world.
