A Opteka High Definition 500mm preset telephoto lens is great for nature and sports photography. The amazing power of this lens gives you the equivalent of looking through a pair of 10x power binoculars. It has a manual preset diaphragm, a rotating tripod mounting collar and a soft lens pouch. Because all Opteka lenses are designed and manufactured with the highest possible degree of consistency, you can swap lenses mid-shoot with no discernable variation in color or effect. The unprecedented purity, color saturation and repeatability of Opteka lenses virtually eliminate the need for lab color timing corrections caused by other lenses. This puts more creative control where it belongs, in your hands. Lens Construction: 7 elements in 5 groups, Angle of View: 5°, Minimum Focus Distance: 33 ft. Focus Modes: Manual focus Minimum Aperture: f/8. 0 Maximum Aperture: f/32. 0, Filter Size: 67mm
