The Canon EW-103 Lens Hood is designed specifically for the Canon RF 28-70mm f/2L USM lens, providing reliable protection against stray light, lens flare, and unwanted reflections that can degrade image quality. By blocking peripheral light sources from striking the front element, the EW-103 helps maintain contrast and colour accuracy across a wide range of shooting conditions. It also offers a degree of physical protection for the front of the lens against knocks and incidental contact. As an official Canon accessory, it is engineered to fit the RF 28-70mm f/2L USM precisely, ensuring no vignetting or interference with the zoom range.
