M12-zu-C-Mount-Adapter zur Verwendung mit M12-Objektiven und C- oder CS-Mount-Kameras

CLA127 is a 3.5mm thick M12-to-C mount adapter for using M12 (S-mount) lenses on C-mount and CS-mount cameras. You thread the M12 lens into one side, screw the adapter into the camera body, and the system is ready. You can remove the adapter later with a standard spanner wrench.

The critical spec here is mechanical back focal length. If your M12 lens has an MBFL under roughly 4mm, it usually cannot reach focus on a C-mount camera because the sensor sits too far away. Telephoto M12 lenses at 12mm focal length and above are the best candidates. Wide-angle M12 lenses usually are not. You can read lens mount guide for the full compatibility breakdown.

The adapter uses machined aluminum construction and stays under 10g. The profile stays at 3.5mm, and the part uses standard M12x0.5 threads on the lens side and 1"-32 TPI C-mount threads on the camera side.

Mechanical fit does not guarantee full image coverage. If the M12 lens image circle is smaller than your sensor diagonal, you will get corner vignetting. You should match image circle to sensor size before you order.

The adapter is in stock and ships same day from San Diego for orders before 12 PM PST. The price is $6.00 per unit, and volume discounts start at 50 pieces.
