Product Highlights
  • Mirror Lens
  • Just 3.0" Wide & 3.5" Long
  • Accepts 30.5mm Filters
  • Requires Camera-Specific T-Mount

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.

Despite this lens' long 500mm focal length, it 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).

        Comments about Bower 500mm f/8.0 Manual Focus Telephoto T-Mount Lens:

        I bought one of these Bower 500mm f/8.0 lenses and I wish that I had saved my money for a better lens.

        This lens is a mass produced piece of junk that does not let in enough light to allow you to take decent quality photos and using a 2.0 X teleconverter with it only lessens the amount of light rendering it a totally useless lens.

        My advise to anyone considering buying one of these Bower 500mm f/8.0 lenses is,.. DON'T,.. you would be much better of buying a $149.00 Canon AF 75-300mm lens as it takes much better quality photos and is auto focus, don't be fooled by the 500mm size of the Bower, what good is size if the photo quality is horrable?

        Save your money for a decent lens and stay away from JUNK like this !

            Comments about Bower 500mm f/8.0 Manual Focus Telephoto T-Mount Lens:

            I just tested this new baby out, it's super light for a tele lens. I've already get info from internet about pro-cons of mirror lens and they are true, so it doesn't surprise me about the slightly less contras, doughnut bokeh - which is for me is a plus/uniqueness.
            it's manual, fix mm, fix F, cheap, T-mount needed.
            it's a good value for money
