The Opteka 6.5mm f/3.5 Fisheye Lens is an excellent addition to any photographer's collection, giving users the ability to expand their creativity and capture incredible scenes from a truly unique perspective.

The minimum shooting distance (just 12 inches) and large depth of field also provide amazing close-up shots.Opteka's super multi-layer lens coating reduces flare and ghosting, a common problem with digital cameras and also creates an optimum color balance.The new version of the Opteka 6.5mm features a removable bayonet lens hood to allow use on full frame DSLR's.SpecificationsLens Construction:10 Elements in 7 GroupsAngle of View:180 degrees diagonalAperture Range:F3.5 ~ 22Minimum Focusing Distance:1 ft / 0.3mLength:10cm / 4 in.Weight:14.6 oz (414g)
