This black LockCircle Camera Body Cap for Nikon F Mount is designed to fit securely on a camera body, as the cap has a hole cut into the flange where the camera locking pin locks inside. This creates a seal that protects the mirror or sensor from dust and moisture, and the cap can only be removed by pressing the release button on the camera body.

The cap is milled from a solid piece of billet aluminum, and has a sanded, textured surface. The knurled edge and the rotary telephone finger-fit design provide a secure and comfortable grip in any climate. The anodizing of the paint makes the surface of the cap scratch-resistant.
