Canon RF3 Body Cap

Fits perfectly and snugly onto the RF mount, giving me peace of mind that the contacts are shielded from dust. The material feels sturdy enough to withstand being tossed in my bag.

The click when it seats onto the mount feels reassuringly solid, and it's snug enough that I don't worry about it popping off in my bag. Keeps the contacts clean between lens changes, exactly what I needed.

Snapped this on right away and it fits perfectly flush against the mount—no wobble at all. Feels solid enough to keep dust out when I swap lenses in a hurry.
