EMF adapter with circuit for M42 lens to Canon EOS

This simple adapter allows the use of M42 thread lenses on your Canon EOS camera with the possibility to detect the correct focus in the viewer.  Other programmes can be set on the lens that detect the camera.

It is an accessory that adapts the mount from the mechanical point of view, but with a small electronic device that allows the camera signal to provide the correct approach when the manual adjustment gets a focused image.  Any automatic feature that requires an electronic connection between the lens and the body is not possible.  There are many good quality 42mm thread lenses that deserve to be used on your Canon EOS camera.
