Lens Description: The Bower 500mm f/8.0 Manual Focus Lens is a catadioptric mirror T-mount lens, precision manufactured in South Korea. 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. T-Mounts are available for all the digital SLR systems, as well as for C-mount systems. However, in every case the fixed f/8 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.
