Related Questions and Answers

Q: 1. Is the iris closed when there is no DC supplied to the lens?

A: The IRIS is usually closed. When power is supplied via the DC cable connected to the camera, the IRIS will open. If you do not want an auto IRIS, I would recommend looking at a manual IRIS lens.

Q: 2. the lens is labled 5-50mm "IR" Varifocal lens... what does the IR stand for? Is this an infrared lens?

A: The Marshall Electronics 3MP CS-Mount 5-50mm IR Varifocal Lens BH #MAVSM5504 is an IR corrected lens which employs low dispersion glass (LD glass) which is a type of glass that greatly reduces Chromatic Aberration. Chromatic Aberration is a type of distortion in which there is a failure of a lens to focus all colors to the same convergence point or image plane.
