Large eyecup designed for the EOS 3, EOS A2/A2E, Elan 7/7E and II/IIE. Keeps out most sunlight and other external light, substantially enhancing viewfinder visibility. It is especially helpful for eyeglass wearers when photographing outdoors. The mount can be rotated for vertical shots.
Note: Eyecup must be slid up when opening or closing the camera's back cover.
