|Manufacturer Part No.||SLY50063|
The Bower 500mm f/6.3 Manual Focus Lens is a catadioptric mirror T-mount lens, delivered in this configuration with a T-mount for Canon EOS cameras. This lens is precision manufactured in South Korea. When combined with the T-mount, this mirror lens mounts to any Canon EOS camera and works on both "full frame" cameras like the 5D as well as the "APS-C" style digital SLR cameras. However, 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.
