From chatting with a Pentax techie quite a while ago, while he checked my K100D...The Pentax lens mount is deliberately built with a weak point (the mounting screws), but strong enough for any normal usage with even the heaviest lenses.
That way if the lens hits the pavement (it happens...) the lens mount will come off and may need to be replaced, but you have a better chance to avoid permanent damage to the camera chassis..
Thanks for the info

I have used 300/2,8 and 500/4,5 lenses a lot with my K10 and K 7 bodies. Never had any problems whatsoever with the the lens mounts !

in the k5/kr (and all other pentax DSLR's for that matter), is the lens mount bolted on a plastic or metal frame?
Interesting question. Why do you ask? Have you had some issues with a lens mount at some stage from a Pentax or another brand?

I've never heard of or seen any Pentax lens mount fail, going back many years to the film days, when lenses were usually far heavier than today. I have confidence in Pentax's ability to engineer the lens mount.
