Surely someone will now start a thread about galvanic corrosion.

It's true, the screws on my K-7 show signs of it. The few that get wet and salty from my hands turn white and the corrosion has to be removed periodically.
--The lens mount on the body is designed to separate from it if the stress is too high, to preserve the integrity of the body and avoid bending it out of shape, which would mean the complete loss of the camera. i think the screws that hold the mount on are designed to fail and break before too much stress is transferred into the body.
That's what i read abt it anyway. Some of the folks here will know a lot more abt it than me.
