  • Bright f1.3 maximum aperture captures clear footage in low light

Focal range and format

The Computar Ganz TG10Z0513AFCS is a 1/3-inch format varifocal lens covering 5–50 mm with a maximum aperture of f1.3. It is built for CCTV cameras that need adjustable field of view in a CS-mount body. The all-glass optics include an aspherical element and a durable metal barrel with locking setscrews. Installers who need a single lens for wide-angle to telephoto coverage will find it suitable.

Iris operation and light handling

The built-in video auto iris adjusts aperture automatically as scene brightness changes, keeping exposure consistent without manual intervention. The f1.3 maximum aperture gathers ample light for low-light surveillance, while the variable focal length lets the installer frame the scene precisely. No external power or control cables beyond the standard auto-iris interface are required for basic operation.

Mount hardware and warranty

The lens ships with locking setscrews that secure focus and zoom positions against vibration, and the CS-mount metal barrel mates directly with compatible camera bodies. A three-year manufacturer warranty covers defects in materials and workmanship. No additional software, adapters or accessories are bundled in the package.

Questions about this item

How do I fit the TG10Z0513AFCS onto a CS-mount camera and what step is often missed?

Screw the lens into the CS-mount thread, then tighten the supplied locking setscrews so the focal setting cannot shift during vibration.

What part of the TG10Z0513AFCS will need attention after long-term outdoor use?

The auto-iris mechanism and its cable are the only moving parts; inspect them periodically for dirt or cable fatigue.

At what focal length does the TG10Z0513AFCS give its narrowest field of view?

The telephoto end of the 5-50 mm range provides the tightest angle of coverage.
