Diaphragm buffer members absorb vibration between the opening members and fixed barrel, reducing lens-barrel noise without rubber deformation.
Stacked lenses collimate light at the lens-barrel interface, while replaceable outer lenses preserve wide-field image quality after damage.
Color-matched mount rings stay visible on the camera and accessory, helping users verify compatibility before attachment.
An aluminum-oxide-bonded metal barrier separates transparent lens regions to block light leakage, reduce cross-talk, and preserve compact emitter-detector layouts.
Two optical systems switch between simultaneous autofocus and selective adjustment to align left and right images for stereoscopic viewing.
Shim-ball alignment and mechanical coupling limit optic motion, compensate temperature effects, and preserve retroreflector precision.
An eccentric engaging portion converts rotary input into optical-axis barrel movement, preserving compact size for precise flange-back adjustment.
A movable reflecting member redirects light for OIS, while perpendicular-axis motion and split lens barrels support compact AF and zoom.
