Such a lens - Sigma 50mm f1.8 - doesn't exist. You must mean the Sigma 50mm f/1.4 EX DG
Originally posted by BigMackCam can you describe in a bit more detail? Will they slot into the mount, but just not lock into place, or is it something else?
Extra detail will certainly be useful.
Specifically, is the lens being physically blocked from mounting properly on the K-3 II, by something like (for example) the pentaprism overhang touching the rear of the lens?
Physically, the lens mount side of the K-3II appears identical to the K-3, so lenses that fit OK on K-3 should mount OK on K-3II.
Or does the problem lens mount properly and lock into place, but then not work? If that's the case, it's either another physical problem with lens or body, or something else.
