PROBLEM TO BE SOLVED: To provide a camera frame assembly having a mechanical shutter blocker which requires only a small space and is movable by a rotation part of a lens assembly. SOLUTION: The camera frame assembly has a frame and a shutter release attached to the frame. The shutter release can be selectively opened from a ready state to a release state. A lens base part joined to the frame defines an optical axis. A lens barrel is movable along the optical axis between a first position and a second position relatively to the lens base part. A twist ring is rotatable from a right-hand configuration to a left-hand configuration through an intermediate configuration in the reverse direction relatively to the lens base part. The twist ring is mechanically linked to the lens barrel, and the lens barrel is moved from the first position to the second position according as the twist ring is rotated from the right-hand configuration to the left-hand configuration. A blocker has a first end joined to the frame, a second end connected to the twist ring, and an engagement part between the ends. The engagement part locks the shutter release in the intermediate configuration and unlocks the shutter release in either of the right-hand configuration and the left-hand configuration.
