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.

EXPANSIVE 180 DEGREE VIEW - The Opteka 6.5mm f/3.5 Circular Fisheye Lens offers an incredibly exciting perspective and takes photography to a range that exceeds the ability of the human eye. Bend the typical view of your photographs and video to the extreme with the ability to capture a full 180 degree panoramic frame. That fishbowl angle, combined with the impressive 11.8-inch focusing distance, allows an incredible depth of field making the 6.5mm the perfect addition to your bag of tricks.

HD SUPER MULTI-COATED OPTICS - In order to assist with the common and annoying problem of flare and ghosting, Opteka's Fisheye lens has been coated with a special layer above the optics to reduce this harmful effect. Additionally, a removable petal shaped lens hood is included reducing further the amount of light directly on the lens. This provides a valuable shelter from unwanted light rays helping you to capture ultra clear and vivid images.
