Featuring a specialized design that is ideal for shooting in the vertical orientation, the ER-hE Eyecup is larger than the standard eyecup for the Canon EOS R3 mirrorless camera. This eyecup has an asymmetrical shape that more effectively blocks stray light along with a 360° rotating design, with clicks at 90° intervals, to suit various ways of handling the camera. It is made from silicone rubber, provides comfortable cushioning around the camera's eyepiece, and is suitable for eyeglass wearers.
