This vintage Kern Paillard Yvar AR 75mm f/2.5 telephoto cine lens is for use with c-mount cameras and adapters. Its focus is a little stiff but fully functional. There are a couple of light scuff marks on the barrel's exterior. There is haze and a fungus spot inside of it. Its aperture adjustment is smooth and its glass is free of any fungus or separation to its elements. There are a few cleaning marks on the front and rear elements. There is no oil on its aperture blades.
