Hi there.
If they can fit onto the old film Pentax SLR cameras, they can fit your K-m - and work as well, provided you know how to.

See here:

This is for M lenses (ones without an A setting on the aperture ring):

This is for M42 screwmount lenses, that need adapters to fit onto the K-mount of Pentax cameras:

Ye. If they are M42 screw mount lenses, you need the M42 to K-mount adapter. Otherwise, just see the sticlky thread in this very forum on the procedures for using the different types of K-mount lenses. Basically, AF lenses work exactly as you'd expect. Lenses that support auto-aperture also work exactly as usual. Lens on which the only way to set the aperture is using the aperture ring require a special procedure to meter that is explained in that thread.
