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

For Canon shooters making the move to the EOS R system, a quality mount adapter is the difference between leveraging years of glass investment or starting over. The Meike MK-EFTR-B sits in that practical middle ground — a fully electronic EF-to-EOS-R adapter that adds a control ring without Canon's price premium. It keeps autofocus, image stabilization, and EXIF data intact, making it a workable daily driver for portrait, event, and studio photographers who built their kit around EF-mount glass and aren't ready to replace it.

The adapter is constructed from metal with a rubber gasket at the rear mount interface, providing basic environmental resistance appropriate for studio and casual outdoor use. The control ring rotates smoothly and can be mapped to aperture, shutter speed, or ISO in-camera — a genuine convenience for video work or zone-based street shooting. At 130g it's unobtrusive in the hand, and the electronic contacts are well-finished, making lens swaps feel secure. It's a straightforward, well-executed piece of glass-preservation hardware for the transitioning Canon shooter.
