The Pro Lens Mount Adapter for Rolleiflex SL66-Series Mount Lens to Canon EF or EF-S Mount Camera from FotodioX allows a Rolleiflex SL66-series mount lens to be used with a Canon EF or EF-S mount camera. It is designed to support focusing to infinity, and is constructed with brass along with stainless-steel mounting rings to provide a durable, yet lightweight camera-to-lens connection.

This adapter does not support electronic communication between an attached camera and lens. After being placed on the front of the adapter, aperture control on a compatible lens would continue to be used. For focus control, the Pro Lens Mount Adapter for Rolleiflex SL66-Series Mount Lens to Canon EF or EF-S Mount Camera features a built-in helicoid that extends and retracts a compatible lens in a manner similar to a Rolleiflex SL66-series camera's focusing rack.

Similar to a Rolleiflex SL66-series camera's lens mounting ring, the Pro Lens Mount Adapter for Rolleiflex SL66-Series Mount Lens to Canon EF or EF-S Mount Camera offers the ability to mount a compatible lens in reverse. By utilizing this feature, the focal length of the attached lens relative to the camera being used is shortened, which can then provide a macro effect.

To help prevent stress on the camera mount if the supported camera and lens combination is to be placed on a tripod, the Pro Lens Mount Adapter for Rolleiflex SL66-Series Mount Lens to Canon EF or EF-S Mount Camera includes a detachable tripod foot that features 1/4"-20 threads.

  A: The Canon EOS-Mount Lens to Canon EOS M-Mount Camera adapter would be for adapting Canon EF/EF-S lenses onto Canons M Mirrorless cameras. This adapter would not let you use EF-S lenses on a full frame camera. Im not aware of an adapter on the market that would allow you to mount EF-S lenses on a full frame camera such as the 5D. Even if you were to find one, the image circle of an EF-S lens will not cover the entire sensor.
