This is a manual focus lens. You can only use the lens in "M" manual exposure mode or "A" aperture-priority mode.
Expand your creativity and capture incredibly unique scenes with the Opteka 6.5mm f/3.5 Ultrawide Fisheye Lens for Canon APS-C cameras. The rectilinear (meaning the scene fills the entire screen), amazingly exaggerated field of view creates a bigger than life perspective, taking your photography into a realm that exceeds the ability of even the human eye. Bend the typical look of your photographs and videos to the distorted extreme thanks to this lens' ability to capture a full 180 degree panoramic frame. (Pro tip: The lens features a minimum focus distance of just 12". In this close focus range, the 6.5mm f/3.5 provides a downright deformed look of any object you put in from of the lens) It's an excellent addition to any photographer's collection, giving them a special fisheye look that few, if any, other lenses can recreate. Opteka's Super HD multicoatings have been employed to suppress flare and ghosting by preventing reflections between the image sensor and lens surfaces. The lens has been designed to maintain a high order of contrast and color fidelity even when shooting in conditions with strong incident backlight.
