M42 Lens to Pentax Macro 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. Doesn't allow focusing to infinity. Only for macro shooting.
