For reports of this lens fouling a K-7 and an H3v, check the 7 Nov. 2011, 11:29 pm post on

I would not find interference with an H3v surprising at all. It was not unusual back in the day to have a lens that would fail to clear the mirror on a camera with a reasonable length mirror (required to avoid top margin black-out with telephoto lenses). I would, however, find it very surprising on an APS-C camera since the mirror should be only about 2/3 as long. That being said, I am not willing to call the two MF Forum user liars.
Along with the K-7, the thread also mentions problems with the K20D with that lens. What is even more puzzling is that there is another thread on MF Forum where a user posts photos from the same lens taken with a Sony A700 FF.
So, when in doubt, do a little visual comparison. Looking at the K10D...Looking at the SV (same as H3v). Now if that is not strange. The leading edge of the mirror on both cameras is about the same depth from the lens flange when raised. The mirror on the K10D (and presumably other Pentax dSLRs is outsized on the short axis.
Dang. Something new to remember...
