Computar Ganz EX2C 2X C-Mount Extender surveillance accessory

Computar EX2C 2X C-Mount Extender

This Computar Ganz EX2C extender fits between a C-mount lens and a compatible camera body. It doubles the effective focal length of the attached lens, providing a narrower field of view for distant surveillance targets. The accessory is manufactured in Japan and carries a three-year manufacturer warranty. It is intended for installers who need extended reach without swapping lenses.

Doubles focal length on C-mount systems

The extender threads directly into the standard C-mount interface on both the lens and camera sides, requiring no additional adapters or power. It preserves the existing lens aperture and focus mechanics while increasing magnification. Builders who need wider coverage or electronic zoom should consider alternative approaches, as this optic only increases focal length by a fixed 2X factor.
