This adapter makes M42 mount lenses (Zeiss, Pentax, Praktica, Mamiya, Zenit) can be used on Pentax PK cameras. 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. You can shoot with manual mode or aperture priority mode . Package includes: Lens mount adapter x1
