FotodioX Macro Reverse Ring for Canon RF (77mm)

The 77mm Macro Reverse Ring for Canon RF from FotodioX allows you to mount a lens in reverse onto your Canon RF mount camera, letting you use the lens for macro photography. The ring is made of aluminum, so it allows for secure attachment of your lens. Once the ring is mounted on the camera, your lens can then be screwed onto the ring via the filter thread of the lens. Any lens with a 77mm filter thread can be attached, and step-up/step-down rings can also be used. And because no other optical components are added with this ring, the image preserves the original optical properties of the lens.
