The Bower Telephoto Lens 500mm f/8.0 Manual Focus Lens is a catadioptric mirror
T-mount lens, precision manufactured in South Korea. It is delivered in
this configuration with a T-mount adapter to fit the Canon EOS system
cameras.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/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.Despite this lens' long 500mm focal length, Bower Telephoto has a
compact 3 x 3.5" size and weighs under 1 pound, making it a bit easier
to handle than normal 500mm refractor lenses (it should be used with a
tripod or monopod in any case). 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.This lens is an ideal candidate for
astrophotography use when mounted to a Vixen GP2 Photo Guider (or other
motorized equatorial telescope mount).- Fixed-aperture 500mm f/8 mirror lens- Multicoated optics- Distinct out-of-focus highlight characterization- Excellent close focusing capacity- Accepts 30.5mm filters at rear of lens barrel- Made in South KoreaAvalailable also in other mount for Telephoto Lens for Canon, Contax,
