ProMaster 4063 機身蓋 適用 Canon RF

Fits snugly on my Canon RF mount with zero wobble, and the spring-loaded center pin makes removal quick even with cold fingers. Definitely keeps the sensor cleaner in my camera bag than the cheap caps I used before.

The plastic feels sturdy enough to handle regular swapping, and it clicks into place with a reassuring snap. I've been using it to keep the sensor clean while switching lenses outdoors, and so far no dust issues at all.

Threw it in my bag between lenses on a dusty hike and the RF body stayed spotless the whole day. The fit is snug enough that I don't worry about it popping off, and it takes two seconds to pop on when I swap glass.
