Product description

• Bower 500mm f/8 Manual Focus Telephoto T-Mount Lens The Bower 500mm f/8 Manual Focus Lens is a classic refractor-style T-mount lens, with an aperture diaphragm in the middle of the lens body to stop down the aperture when necessary.  However, it is assumed that much of the shooting with such a lens will be at its maximum f/8.0 aperture, with a tripod, monopod, or other such support. When combined with the T-mount to fit your camera system, this super telephoto 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, and even for C-mount systems.  However, in every case the 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. This lens' sophisticated achromatic refractor design yields images with pleasing peak contrast and well controlled flare.  It can be used at maximum aperture on a very bright day for some images of moving subjects. This lens can also be used as a handheld telescope by adding Lumicon's LA1070 adapter along with a 1.25" 45°/60°/90° diagonal and any 1.25" eyepiece, or for astrophotography by using on an SLR mounted to a Vixen GP2 Photo Guider or other motorized equatorial telescope mount.

• 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.
