Key features

• •ADVANCED OPTICS: Featuring an optimized design, this lens uses mirrors and a series of 7 optical glass elements in 6 groups to reduce chromatic and spherical aberrations. A anti-reflective coating suppresses lens flare and ghosting for increased contrast and color fidelity.
• •SUPER ZOOM: Manual focus 420-800mm or 840-1600mm with the 2x converter, this lens is not only a superb long range choice, but also performs well in a variety of scenes from sports and surveillance to everyday shooting.
• •SOLID CONSTRUCTION: Full metal body and rear mount allow this lens to withstand wear and tear much better than plastic lenses while commanding a rugged, solid feel when using.
• •NEW AND IMPROVED - The Newly improved 2017 Digitalmate Super Zoom 420-800mm Lens incorporates multi coated glass optics for the sharper images. Its 4 Elements in 2 groups have been digitally-optimized to give the best image possible without braking the bank. A built in Rotating tripod mount has also been added to help stabilize the lens especially when using the 2x Tele Converter which increases the zoom to an incredible 1600mm.
• •TELE-CONVERTER - The Opteka 2x High Definition Tele-Converter is for use with T-Mount manual focus lenses. It will multiply the focal length of your existing lens by 2x, and will cut back the amount of light by two f/stops. For example, using a 2x tele-converter with a 500mm lens will effectively increase the focal length to 1000mm.
