Weird lens issue.

is it the Sigma 24mm Super-Wide? Mine goes on to a K-1 mk1 ok, and a K-20. Have you tried holding down the lens release button while you mount the lens. For some reason I had to do this at first time, but not since.

Sounds like the mount might've been damaged at one point. Happened to my FA50/1.4, it wouldn't click after it met the cobbles in Bruges.
Z-1p, K-1, P50
F50 1.7. SMC-FAs 24, 35, 50 1.4, 85, 135. HD-FA15-30, DFA24-70, D-FA*70-200. The SMC-FA Limited Trinity.

Some Mamiya and some Nikon, and a Canon T70.

I've got a Cosina 24mm f2.8 from film days. It fits snugly on my K20D as well as film cameras but resisted so much when trying to mount it on the K3 that I haven't dared try to force it all the way. Tolerances have to be tight for a lens mount. I assumed that Cosina had slightly wider manufacturing tolerances than Pentax, most of the time there would be no problem but if you had a lens at the extreme end of their tolerances and a camera at the opposite end of Pentax's tolerances you'd be out of luck.
