Thomas ★★★★★

Finally, an adapter that lets me use my existing EF lenses on the RF mount without losing any image quality. The drop-in variable ND filter is incredibly convenient for quickly adjusting exposure in changing light, and it feels solidly built.

Emma ★★★★★

Switching between ND strengths is so much faster with the variable filter built into the adapter itself. The drop-in design keeps my EF glass perfectly balanced on the EOS R body.

Hannah ★★★★★

Finally, a clean solution for using my EF lenses on the RF mount—the variable ND is incredibly smooth to adjust even with gloves on. No more fumbling with separate filter rings.
