Canon 2377A001 Eg Eyecup for EOS Cameras

The Canon 2377A001 Eg Eyecup is a simple but purposeful accessory designed to enhance the viewfinder experience on Canon EOS-series cameras. Made from soft, hollow rubber, it cushions the area around the eyepiece to provide a more comfortable and stable contact point for your eye, which is especially beneficial during long shooting sessions such as events, wildlife photography, or studio work. The pliable rubber also makes it friendly for photographers who wear eyeglasses, conforming around frames without creating pressure points.

Beyond comfort, the Eg eyecup serves a practical optical purpose by helping to shield the viewfinder from stray ambient light that can wash out the viewfinder image and interfere with accurate exposure evaluation. It fits Canon EOS 1D, 1Ds, 5D, 5DS, 6D, and 7D series bodies, attaching directly to the eyepiece frame without any tools required. As a genuine Canon accessory, it matches the fit and finish of the original eyecup that ships with these cameras, making it an ideal replacement or spare.
