Q: 4. 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.
