Bower 500mm f/8.0 overview

  • 1Description

The Bower 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 Minolta MD system cameras.  The fixed f/8 aperture is not communicated to the camera body, and as such you can only use the lens in "M" manual exposure mode (or "A" aperture-priority mode upon applicable cameras).

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 either 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).

    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.

  • General Brand T-Mount SLR Camera Adapter for Minolta MD Cameras

    Ultratelephoto photography is easily achieved with your telescope and Minolta MD camera by purchasing this T-Mount Adapter for Minolta MD Cameras.  You'll need to take precautions to minimize vibrations, such as locking up the mirror if possible as well as using a cable release or remote control to fire the shutter.

    First, remove the eyepiece.  Next, attach the SLR camera adapter where the eyepiece would normally be attached to the telescope, and screw in this T-mount adapter to the opposite end of the SLR camera adapter.  Now you can attach your camera to the T-mount and you are ready to begin taking pictures!

    In addition to being used with telescopes, there are many old and new T-mount lenses which are installed to your MD camera by adding this T-mount adapter to the rear of the lens and installing lens/adapter upon your camera.

    Note: NOTE: Your camera will need to be in fully manual exposure mode, although some cameras may also work in aperture-priority autoexposure mode.  Additionally, if there is a switch on the camera which chooses the focus mode, that switch must indicate manual focusing.
