Camera Lens & Accessories

About

Camera lens and accessory parts protect the lens, improve handling, help adapt gear, and replace small pieces that are often lost or damaged. Common items include front lens caps, rear caps, lens hoods, UV filters, circular polarizer filters, neutral density filters, step-up rings, step-down rings, mount adapters, tripod collars, lens cases, focus grips, zoom rings, bayonet mounts, screws, and protective covers. The most important detail is the exact lens model. A lens accessory may depend on the camera mount, lens diameter, filter thread size, lens hood bayonet shape, collar foot, or rear cap type. A 52 mm filter will not fit a 58 mm lens thread. A hood designed for one focal length may block the image on another lens. A rear cap for one mount may not protect the contacts of another. Customers often ask what lens accessories actually do. A lens cap protects the glass during storage. A rear cap protects the mount and contacts when the lens is off the camera. A lens hood blocks stray light and helps protect the front of the lens from bumps. A UV or clear filter adds a protective layer. A circular polarizer helps reduce reflections. A neutral density filter helps control light for video or long-exposure work. If you are using a compact rugged camera instead of an interchangeable lens camera, lens parts are usually more limited. Lens protectors, filters, housing windows, and small covers may fit better under action camera parts , especially when the camera uses a sealed body or model-specific frame. Before ordering a cap, filter, or hood, look for the filter thread size printed on the front ring of the lens. It is usually shown with the diameter symbol followed by a number in millimeters. If the size is not visible, check the lens manual or the lens model listing. Do not measure the outside of the cap with a ruler unless you have no other option, because cap shape and clip style can vary. Mount adapters need extra care. They allow one lens type to attach to a different
