M42 - K mount adapter
This lens mount adapter allows M42 Universal Screw Mount to fit onto a Pentax
K mount adapter. Although the lens will fit physically, automatic diaphragm,
auto-focusing, or any other functions will not operate correctly while using
this adapter. In this case "stop-down mode" will need to be used when metering
since the lens does not have the ability to have its aperture controlled by
the camera body.
