The BASEDEALS extreme 650-1300mm f/8-16 Manual Focus Lens is an economical way to achieve some ultra-telephoto photography, all the way up to 1300mm. It is an amazing photographic tool that provides a maximum of versatility for anyone shooting at a distance from their subject, including sports and wildlife photography. It's compact (just 18.5"/29.7cm long) and it focuses as close as 16.25' (4.95m). The aperture range is f/8.0 to f/16.0. This manual focus lens has an aluminum alloy body with fully multi-coated low-dispersion optical glass, and a 95mm front filter thread.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 autoexposure 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.
