This is an Ultra wide lens and is based on 35mm or full-frame format. It is wider than 24mm. Ones of this type will give a distorted image compared to a non-fisheye which will keep perspective normal. Generally they can focus much closer than a standard or regular wide-angle lens. In some cases, the filter is either built-in or screws in to the rear of the lens. If you use this lens on a less-than full-frame camera, you will have to multiply the focal length by a factor based on the exact format you are shooting. In most cases, this is about 1.5x, but can vary slightly. Item is in Excellent used condition. No dust, scratches, hazing, or fungus in lens. Exterior is in beautiful condition, aperture feels to factory specs and focus is smooth. Photos taken in house. Lens includes: Lens Cap, Rear Lens Cap, HK-9 Lens Hood.
