The included Opteka 2x teleconverter effectively doubles your zoom converting this lens to a 650-2600mm Super Telephoto!

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.

Because all Opteka lenses are designed and manufactured with the highest possible degree of consistency, you can swap lenses mid-shoot with no discernible variation in color or effect. The unprecedented purity, color saturation and repeat-ability of Opteka lenses virtually eliminate the need for lab color timing corrections caused by other filters. This puts more creative control where it belongs, in your hands.

• ADVANCED OPTICS: Featuring an optimized design, this lens uses a series of 6 optical glass elements (one SD super-low dispersion) in 5 groups to reduce chromatic and spherical aberrations throughout the aperture range. A high definition anti-reflective coating suppresses lens flare and ghosting for increased contrast and color fidelity.
• SUPER ZOOM: 650-1300mm or 1300-2600mm 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 lunar shots.
• 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.
• MANUAL FOCUSING: This lens has preset f-stops that correspond with the focal length at which you are shooting. An index for distance and diaphragm scale is inscribed on the lens barrel to coordinate focal length and aperture.
