● This is a "rear cap" to protect the back of the camera lens. It's a user-friendly compatible product. When changing lenses, having a spare cap on hand gives you peace of mind. ● Not for Micro Four Thirds or Four Thirds. Micro Four Thirds versions are listed separately. There are no dedicated Four Thirds caps, but the "OM" caps I sell seem to work. ● Also available in sets of 2, 3, and 5.
