Computar M6Z1212-3S CCTV Lens

The Computar Ganz M6Z1212-3S is a manual-zoom CCTV lens built for 2/3-inch format cameras. It covers a 12.5-75mm focal range with a fast f1.2 maximum aperture. Manual controls handle zoom, focus and iris adjustment. The unit is made in Japan and carries a three-year manufacturer warranty.

C-Mount Integration and Build Flexibility

The lens uses a standard C-mount thread, so it fits directly onto any compatible camera body without adapters. Locking set screws secure the zoom and focus positions once set, preventing drift in vibration-prone installations. Manual iris operation removes the need for auto-iris wiring or camera-side control logic.

Suited for Machine Vision and Fixed Surveillance

This lens suits integrators who need a variable field of view in inspection, robotics or analogue surveillance roles where precise manual setup is preferred. Buyers who require motorised zoom, auto-iris capability or a different sensor format should look at alternative models.

Questions about this item

How far can the 12.5-75mm zoom reach before the angle of view stops narrowing?

The lens zooms continuously from 12.5 mm to 75 mm, so the longest focal length is 75 mm.

Does the iris mechanism add noticeable heat or noise during all-day operation?

The iris is manually operated with no motor, so it produces no audible noise and negligible heat.

Which camera body mount is required to attach this lens?

A camera with a C-Mount thread is needed; the lens includes locking set screws for secure attachment.
