        • 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.
        • CONSISTENT AND SHARP IMAGES - Because a single aspherical element is utilized in the lens, this helps to reduce aberrations while maintaining a consistent illumination for sharpness around the entire image edge. Because there is so much detail in the frame of the fisheye with its wide angle view, this welcome addition is a helpful tool to create high quality and consistent images every time.
        • DURABLE HEAVY DUTY CONSTRUCTION - With an aluminum alloy lens mount, a super strong connection between lens and camera ensures your Opteka Fisheye will hold up against wear and tear and keep you capturing incredible images for years to come.
        • INCLUDED - Opteka 6.5mm f/3.5 Circular Fisheye Lens for Canon EF, Front and Rear Lens Caps, Lens Hood, Lens Pouch, 5 Year Warranty
