Pro Optics 420-800 f/8.3-16 Vari Zoom Lens

T-Mount Lens which will fit most 35mm SLR Cameras by adding the proper T-Mount. This inexpensive super telephoto vari-zoom lens has an amazing zoom range from 420-800mm! The lens uses all glass optics which are multi-coated to reduce the chance of lens flare or ghost images caused by reflections. The simple traditional T-mount adapted lens is compact and light weight. There is a zoom lock located at the middle of the lens barrel that allows the lens to be locked at any focal length. Aperture is fixed and the Pro-Optic Vari-zoom lens should be used with cameras set to a shutter priority mode.
