ECL-358AIVB: 3.5-8mm Auto-Iris Varifocal Board Camera CCTV Lens

Designed for Board Cameras

This lens is designed for board cameras (it is not a C- or CS-mount style lens).  Since it uses an auto-iris to control lens aperture, it works best with a board camera that auto-iris control circuits (there is no way to adjust the lens' iris without auto-iris control).
