The aperture required will need to be set manually on the M42 lens and auto-exposure will then function. Auto-focusing will not operate while using this adapter and manual will need to be used. Focussing to infinity and TTL flash metering is preserved with this adapter.

To Mount: Mount the M42 Lens onto the adapter, then mount them onto the Canon camera. Set the aperture on the lens, switch the camera on, choose any program from the Mode dial, focus the lens manually and shoot.

To Remove: Remove both lens and the adapter together from the camera in the same way you would remove a lens. Then remove the adapter from the lens by depressing the lock on the mount, rotating the mount on the lens and removing.

Infinity is achieved with this mount adapter.
