The58mm 3-in-1 Rubber Lens HoodbySenseiblocks unwanted stray light from entering your camera's lens to minimize flare and glare. The 3-in-1 hood is extendable and provides three stages of shading. At its collapsed setting, the hood provides shading for 28mm lenses (in full-frame format, 18mm with APS-C format sensors), without vignetting. At its middle stage, it covers lenses up to 50mm (full-frame format, 35mm with APS-C). Fully extended, it covers lenses 70mm and up (full-frame format, 55mm with APS-C).
Additionally, in its collapsed stage the hood protects your lens from accidental impact, and saves space during transport. It attaches to your camera's lens via the threaded internal ring. The hood's ridged interior helps minimize light reflection. The hood's internal ring will accept a 55mm lens cap, which further allows you to protect the lens from dust, fingerprints, and scratches when the lens is not in use. The ideal lens cap to use for this is a center-pinch (push-on) type.
