Thanks, yeah gave it a good look at, the lens is securely mounted as far as I can see, everything looks normal and I've tried it with mulitple lenses! I think something has snapped on the camera body, cant remember how it was before enough to think of a fix, but in the local camera shop this morning I was offered a real Pentax body for 30 so figure I may just go for that!
