M42-EOS Lens Mount Stepping Ring, M42-EOS

1) Make M42 mount lenses (suitable for Zeiss, Pentax, Praktica, Mamiya, Zenit) can be used for Canon EOS cameras

2) There is no ROM connection on the ring so diaphragm control of the lens is set manually

3) It is possible to use Macro rings and other accessories

4) Made of Metal

5) Size: 65x65x8mm

* Note:

-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
