Material: Brass

Description: The adapter is suitable for M42 type lenses and Pentax PK DSLR and Film SLR cameras, as well as for Ricoh, Chinon, Cosina, Sigma, Pearl River, Phinex (provided that the camera body accepts Pentax PK lenses). It should be noted that the automatic aperture and autofocus will not work properly when using this adapter. The "stop operation mode" should be used during metering, as the lens cannot have its aperture controlled by the camera body. It is possible to shoot in manual mode or aperture priority mode (A/V).

Instructions for Use:

• Align the red marks of the adapter and the lens mount together.
• Rotate the adapter clockwise until it clicks into place.
