A bayonet lens mount is a common method of attaching a camera lens to a camera body. The lens is inserted into the mount and given a short twist to lock it securely in place, ensuring stability and precise alignment. Most bayonet mount systems are proprietary, meaning lenses from one manufacturer generally cannot be used on another brand's cameras. This mounting method is popular for its speed, reliability, and ease of lens changes, making it the preferred choice for professional and enthusiast photographers across various genres.
