Pentax K20D & M42 Lenses Infinity Focus Question

Hi guys, this is my first post, and forgive me for a very basic question.

With correct M42-Pentax adapter that fits entirely inside the camera, at any given M42 lenses, without any modifications, how much percentage of those lenses that will focus to infinty ?

Regards

I too am getting an M42 lens first time.
What precautions are to be taken to avoid jamming of the 'pin' on the mount? Like, if it is okay to switch between A/M when it is mounted? Thanks

The pin does not contact the adapter or any part of the mount and there is nothing inside the camera for it to jam against. It is perfectly OK to use the A/M switch with the lens on the camera.
