Bower T-mount 650-1300mm F/8 Zoom Lens with Case, Requires T-Mount
This Bower T-mount 650-1300mm F/8 Zoom Lens with Case is an economical way to achieve some ultra-telephoto zoom photography, all the way up to 1300mm. This is a T-mount lens, which means that aperture is not communicated to or controlled by the camera body, and as such must be used only in aperture-priority auto exposure mode or in the manual exposure mode. There are T-mounts available for every modern DSLR system, as well as for older film cameras and even C-mount cameras. It will work on both 35mm/Full Frame Sensors as well as the smaller-format APS-C cameras, but has only one effective aperture at any focal length, which varies from f/8 at 650mm to f/16.0 at 1300mm. This lens requires bright light and a high ISO setting on the camera to get a fast shutter speed, and needs a sturdy tripod or monopod to deliver proper, sharp results. This lens is offered in new condition only with free shipping!

From the Manufacturer

This extreme 650-1300mm f/8-16 Manual Focus Lens from Bower is an economical way to achieve some ultra-telephoto photography, all the way up to 1300mm. This is a T-mount lens, which means that aperture is not communicated to or controlled by the camera body and as such must be used only in aperture-priority auto exposure mode (if your camera has it) or in the manual exposure mode.

It will work on both "full frame" digital cameras as well as the smaller-format APS-C (15 x 22mm) cameras, but has only one effective aperture at any focal length, which varies from f/8.0 at 650mm to f/16.0 at 1300mm. That's not much of a hindrance, however, as you'd likely use this lens at its relatively small maximum aperture in any case.

This lens requires bright light and a high ISO setting on the camera to get a fast shutter speed (or fast film in a film camera) and needs a sturdy tripod or monopod, but can deliver very sharp results if used properly.
