Adapter M42/EOS Adapter
This hard wearing bronze mount adapter ring allows you to use Pentax, Praktika and Zenit lenses with a M42 screw mount on your Canon EOS camera, saving you the expense of a costly and irreversible conversion.
To use, simply attach the ring to your lens and then the lens to the camera. When you have finished remove both together. It’s as easy as that!
On compliant models this enables you to get stop down manual exposure and aperture priority exposure.
Compatible with Canon DIGITAL and FILM cameras
