Small silver CCTV lens, CS mount, 2.6mm f1.6, made in Japan

Computar Ganz

Computar Ganz T2616FICS 1/3" 2.6mm f1.6 CCTV camera lens

SKU CH-33NA-4AAPS

A 1/3" CS-mount CCTV lens with a fixed 2.6mm focal length and f1.6 manual iris

  • 1/3" format matches many CCTV cameras
  • 6mm focal length gives wide field of view
  • f1.6 aperture captures bright images in low light
  • CS-mount fits standard surveillance housings
  • Manual iris lets you set exposure by hand

Fixed 2.6 mm focal length for wide coverage

The Computar Ganz T2616FICS is a monofocal CCTV lens built for 1/3" format sensors. Its fixed 2.6 mm focal length suits installers who need a consistent wide field of view in analog surveillance setups. The CS-mount design fits standard CS-mount camera bodies directly.

Manual iris and f1.6 aperture adapt to light changes

A manually operated iris lets the installer set depth of field and exposure once during commissioning. The f1.6 maximum aperture passes more light to the sensor, improving low-light usability without electronic gain. No auto-iris wiring or power is required.

CS-mount threads on in seconds; check sensor format

The lens screws onto any CS-mount camera without adapters. Verify the camera uses a 1/3" sensor so the image circle matches; larger sensors will vignette. Fixed focus means no focus-ring drift, but the focal length cannot be changed after installation.

Questions about this item

Will the manual iris on the T2616FICS need periodic adjustment or replacement?

The iris is manually operated and has no motor or auto-iris circuitry to fail, so it only needs occasional cleaning of the aperture blades.

What limits image brightness first when the T2616FICS is used continuously in bright daylight?

The fixed f1.6 aperture cannot stop down further, so the sensor or external housing must handle excess light.

Does the T2616FICS generate noticeable heat or draw extra power during all-day operation?

The lens is purely passive glass and mechanics; it produces no heat and draws no power of its own.
