Designed specifically for vertical shooting, the ER-hE Eyecup is a larger alternative to the standard eyecup for the Canon EOS R3 mirrorless camera. Its asymmetrical shape helps block stray light more effectively, while the 360 rotating design, with clicks at 90 intervals, adapts to different shooting angles. Made from soft silicone rubber, it offers comfortable cushioning around the eyepiece and is also ideal for eyeglass wearers.
