FOR CM-EF- R Electronic Lens Mount Adapter — Auto Focus, IS Function & Aperture Control for EF/EF-S

The FOR CM-EF- R lens mount adapter allows EF/EF-S lenses to maintain electronic autofocus, pass through IS (image stabilization) capability, and support aperture control when attached. It preserves electronic communication between lens and camera so AF, IS and diaphragm adjustments continue to work as designed, enabling use of EF/EF-S optics without losing those electronic functions.
