C’ and ‘CS’ mount devices all have the same screw thread. Some older or larger lenses are C-mount so will fit on both C and CS-mount camera bodies (with a 5 mm adaptor ring). Most recent small lenses are CS-mount so are fine on CS camera bodies but will never achieve focus if used on a C-mount camera.

The simplest CCTV lens is a piece of glass to focus the light from the outside world onto the camera’s imaging sensor. This lens’ only adjustable mechanism is its focus-ring, part of the barrel body, which you turn until your image is as clear as possible. Incidentally, use the sharpest test monitor you can. For instance, black & white tubed monitors can be much sharper than colour LCDs. The amount of light let through to the camera cannot be controlled by this simple lens.

Upgrading to a lens with a manually adjustable ‘iris’ is only a benefit during set-up, so both are best suited to scenes where lighting is constant. To a limited degree, an automatically adjusting electronic shutter in the camera might accommodate changing brightness. However, in scenes where it varies significantly, electronic iris features are better replaced by auto-iris lens.
