Product Description
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.
