Meike MK-EFTR-B Control Ring Adapter for EF/EF-S Lens to EOS-R Cameras

Adapter allowing Canon EF/ EF-S lenses to fit on Canon EOS-R mount mirrorless cameras incl. electronic contacts to facilitate communication between EOS-R cameras and EF/EF-S lenses. Durable metal construction, weighting 130g and measuring 74.4x24 mm.

What the adapter is for

The adapter fits Canon EF / EF-S mount lenses to a Canon RF mount body. Infinity focus is retained, so the lens works across its full range just as it would on its original body.

What it does

Alongside full autofocus and electronic aperture support, the adapter carries a programmable control ring just like native RF lenses — assign it ISO, exposure compensation or aperture.
