Canon R-F-4 EOS M Compact Systems Camera Cover

The Canon R-F-4 is the official body cap designed for Canon's EOS M series compact system cameras. Its purpose is straightforward but essential: it protects the camera's EF-M lens mount, sensor, and internal components from dust, dirt, and moisture whenever a lens is not attached. Whether you are swapping lenses in the field, packing your camera for travel, or storing it between shoots, the R-F-4 provides a secure barrier that keeps the sensitive interior of your camera clean and protected.

Made in Japan, the R-F-4 uses the standard EF-M bayonet mount interface, so it twists on and off with the same motion as attaching a lens. The fit is precise and secure — it will not fall off in a bag or during transport. It is an inexpensive but worthwhile accessory to keep as a spare, especially if you own multiple EOS M bodies or frequently shoot with a single camera and multiple lenses. Having an extra body cap on hand means your camera body is always protected, even when you are using a different lens combination.
