Canon 2637A001 - ET-60 Lens Hood - 75-300mm Lenses

The Canon ET-60 is a dedicated lens hood designed for Canon's EF 75-300mm f/4-5.6 II, II USM, III, and III USM zoom lenses. Its primary purpose is straightforward: it blocks stray light from entering the lens at oblique angles, which reduces flare, ghosting, and the loss of contrast that can occur when shooting toward or near bright light sources. This is especially valuable at the longer focal lengths of a 75-300mm zoom, where even modest flare can noticeably degrade image quality. The tulip-petal shape is optimized to shade the lens without intruding into the frame at any focal length in the zoom range.

Beyond optical benefits, the ET-60 serves as a practical first line of physical defense for the front lens element, shielding it from bumps, stray fingers, and light moisture. It uses Canon's standard bayonet mount system, so it clicks on and off in seconds and can be reversed onto the lens barrel for compact storage. The hood is lightweight plastic, adding negligible bulk to an already portable telephoto zoom setup. One important compatibility note: the ET-60 does not fit the IS (Image Stabilized) versions of the 75-300mm, which require a different hood, so buyers should verify their exact lens model before purchasing.
