Canon 드롭인 필터 마운트 어댑터 EF-EOS R (원형 편광 필터 포함)

I was worried about losing autofocus when adapting my old EF lenses, but this adapter locks on just as fast as native RF glass. The built-in circular polarizer is a lifesaver for landscape work, no more fumbling with a separate filter in the field.

The drop-in filter design is so convenient—I can swap the circular polarizer without touching the lens itself. My EF lenses feel native on the EOS R body now, and the adapter is solid with no wobble.

Finally, no more bulky adapters—this mount lets me use my old EF lenses on my R body with a smooth, built-in polarizer. The drop-in filter design is genius for controlling reflections on the fly.
