Adapter M42 Lens to CANON EOS AF Check new
This is the Second Generation AF confirm adapter ring with built in circuit board allows you to use your M42 lens on your Canon EOS EF 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!
Built-in circuit board tricks your camera into believing the lens is manual focus mode so that you can see the in-focus light indicator through the view finder.
