Computar Ganz T0812FICS CS-mount CCTV lens 8mm f1.2

Computar Ganz

Computar Ganz T0812FICS 1/3" 8mm f1.2 CS Mount CCTV Camera Lens

SKU CH-8WMH-QKGX0

A CS-mount CCTV lens with a fixed 8 mm focal length and manual iris control for 1/3-inch format cameras

  • 1/3" format fits compact CS-mount cameras
  • 8 mm focal length gives fixed field of view
  • f1.2 aperture gathers light for low-light scenes
  • Manual iris lets you set exposure precisely
  • Optimised for visible and near-IR spectrum

Lens format and mount

This Computar Ganz T0812FICS lens uses a 1/3 inch format and a CS mount for CCTV cameras. It suits installers who need a fixed focal length on analog surveillance systems. The manual iris gives direct control over exposure without auto-iris wiring. Buyers who want motorised zoom or auto-iris operation should look elsewhere.

Focal length and aperture

The fixed 8 mm focal length and f1.2 maximum aperture replace variable-focal or slower lenses when the field of view and low-light needs are known. The jump is worth it when a single, wide-angle view covers the scene and the installer prefers a set-and-forget optic. The lens is optimised for visible and near IR spectrum use.

Installation and common issues

CS-mount threading makes attachment straightforward on compatible cameras. The manual iris ring is adjusted by hand, so no extra cables or power are required. The most common issue is confusing CS mount with C mount, which changes the flange distance and prevents focus. Ensure the camera uses CS mount before fitting.

Questions about this item

Will this CS-mount lens fit my 1/3" format camera?

Yes, the T0812FICS is built for 1/3" sensors and uses the standard CS-mount thread, so it threads directly onto any compatible CS-mount camera body.

How do I set the aperture on the manual iris ring?

Rotate the iris ring by hand until the image brightness looks correct on your monitor; the ring has no click stops, so adjust slowly and re-check after the camera auto-exposure settles.

Does the fixed 8mm focal length ever need recalibration?

No, the monofocal design has no moving zoom elements, so the 8mm field of view stays constant; only occasional cleaning of the front glass is required.
