The S2123 is the camera-side bayonet holder for Leica M-mount camera bodies on MicoMova or SWEBO mini view cameras. It connects the body to the rear standard through Type 1 bellows; the selected camera platform determines the available movements.
Camera mount and bellows
Choose this holder for Leica M camera bodies. Viewing and focusing depend on the body; mechanical mounting does not provide rangefinder coupling. Type 1 identifies the rear bellows connection, not its length.
Orientation and modular setup
The camera system's rear rotation and lock allow a 90° change between landscape and portrait orientation. Camera bayonet holders of the same bellows type can share one bellows. Changing to another type requires the matching holder and bellows; the front lens-board interface remains common.
Configuration
The camera platform, bellows, lens board, lens and camera body are configured separately. Complete assemblies in the photographs show the holder in use.
Check your optical setup
The holder provides a mechanical body connection, not electronic control. Shutter operation, infinity focus and usable movements depend on the camera, lens flange distance, rear clearance, image circle and bellows extension.
