An upgraded replacement and is compatible with the Sony FDA-EP19 Eyecup to provide extended eye relief and viewing comfort. The ProMaster 72927 eyecup has a soft cushion surrounding it for comfortable viewing, especially for eyeglass wearers. It helps to shield light, making it easier to see the viewfinder. It protrudes further from the back of the camera than the standard eyecup, blocking out extraneous light and helping to keep the viewer's eye, face, and nose further from the back of the camera for greater comfort. Please see the specifications for a list of compatible cameras.
