Bower 500mm f 6.3 Mirror Lens with Pouch

Bower T-Mount 500mm f/6.3 Mirror Lens with Case, Requires T-Mount.

Bower Case - Front Cap - Bower Warranty.The Bower 500mm f/6.3 Manual Focus Lens is a catadioptric mirror T-mount lens. When combined with the T-mount to fit your camera system, this mirror lens mounts to camera and works on both "full frame" cameras as well as the "APS-C" style digital SLR cameras. However, in every case the fixed f/6.3 aperture is not communicated to the camera body. As such, you can use the lens in "M" manual exposure mode or "A" aperture- priority mode only.This lens has a broad diameter and stocky build, making it a bit easier to handle than a normal refractor lens. It also has a much different rendering of out of focus areas than a normal lens; highlights will be doughnut-shaped rings with more saturation and contrast on the edge of the ring than on the center.
