FotodioX Lens Mount Adapter (M39 to Canon EF/EF-S, v10 Chip)

This FotodioX Lens Mount Adapter allows an M39-mount lens to be used on a Canon EF/EF-S-mount camera, utilizing a built-in generation v10 chip in the adapter that enables focus confirmation. This feature allows focus to be quickly and accurately achieved through a compatible camera's viewfinder or live view feature. An aluminum alloy lens mounting ring provides a durable, lightweight camera-to-lens connection.
