This Vello Lens Mount Adapter allows a Leica M-mount lens to be used on a Canon RF-mount camera. It is designed to support focusing to infinity, is constructed from zinc alloy, and utilizes an aluminum alloy mounting ring to provide a durable, yet lightweight camera-to-lens connection.

When an image is taken with this lens mount adapter, a matte black internal coating minimizes the potential for reflections within the adapter barrel, which could otherwise result in unwanted glare within the image.

Q: 4. Can this Adapter be used on a Tamron 18-400mm f/3.5-6.3 Di II VC HLD Lens for Canon EF to Canon R5?

A: The adapter will work, but I wouldn't suggest this. The lens is an APS-C (Cropped) while the R5 has a full frame sensor. Thus using this lens on the R5 will cut your resolution by a large amount, potentially getting a heavy vignette. This also doesn't include AF performance and accuracy which also may vary.

Q: 5. Can not make the shutter work in manual- what I am missing?

A: The Vello Lens Mount Adapter for Canon FD-Mount Lens to Canon RF-Mount Camera does not communicate with the camera. S0, the camera does not know a lens is on the camera. For this reason, you need to go into the menu and set the camera to Release shutter w/o lens.

A: The R6 MK II will work with this adapter, however you need to go into the camera's settings and enable it first. Otherwise the camera's shutter will not go off. Go into your menu by pressing the menu button. Then scroll over to the Custom menu (The far right orange colored tab ) and go over to page 4. You will see "Release shutter w/o lens". It's disabled by default. Once you enable it, you should be good to go.

A: You will not be able to change the aperture on your Canon EF 16-35mm f/4 L IS USM using this manual Vello EF to L-mount adapter. This is due to current EF glass requiring electrical communication and control over the lens in order to change its aperture, which this adapter lacks.
