The Eyecup ER-iE is designed for the EOS R1's Eye Control AF. It includes a large silicone rubber eyepiece that reduces external light interference, enhancing line-of-sight detection. This results in improved precision of Eye Control AF and electronic viewfinder (EVF) visibility under different shooting conditions.
The asymmetrical design and 360° rotation mechanism with click stops every 90° provide optimal comfort and ease of use, especially for vertical shooting.
