Description

The Opteka 650-1300mm high definition manual focus super telephoto zoom lens is perfect for the professional and amateur photographer alike. Using a 2x tele-converter with a 650-1300mm lens will effectively increase the focal length to 1300-2600mm. A lens set to f/8 will now be f/16. There is a built-in, rotating tripod mount for easily attaching to your tripod or monopod. It's an extremely powerful telephoto zoom lens with the versatility that you need. This lens is great for the wildlife or nature photographer who wants to be hidden while taking photos of the subject. When combined with the included 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. You can use the lens in "M" manual exposure mode or "A" aperture-priority mode only. Advances in ultra high-index / low-dispersion optical glasses, new barrel materials, and exotic anti-reflection coatings, along with the latest in computer-aided-design / computer-aided-manufacturing, are combined to produce lenses of unprecedented quality. Diamond-cut from crystal-clear, water-white optical glass, Opteka lenses are ground and polished to a precise precision. This puts more creative control where it belongs, in your hands. Bright sunlight and a sturdy tripod is recommend when using this lens.
