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.

M42 - K mount adapter specifications:

Adapter Type M42 Universal Screw Mount to Pentax K Mount adapter
Lens Compatibility All M42 screw mount lenses
Camera compatibility Pentax K mount bodies, MF SLRs, such as K1000, ME super, DSLRs such as *ist DS, and *ist D
Focus Range Limited
Allow Metering Stop-down metering, camera dependant
TTL flash metering Yes
