The Canon EC Rubber Frame is a professional viewfinder accessory designed for use with Canon dioptric adjustment lenses on select DSLR and SLR camera models. This soft rubber frame replaces the standard eyecup and provides comfortable cushioning around the camera's eyepiece, making it particularly useful for eyeglass wearers. The frame helps to block stray light that could interfere with proper focusing and composition through the viewfinder.
