Avoid unwanted glare and isolate your LCD with the SHAPE Viewfinder for Sony Alpha series cameras and other 3" screens. In addition to blocking out distracting light, the adjustable diopter allows you to focus on your subject more easily. Secure your viewfinder with the included mounting plate screws into the 1/4"-20 thread on the bottom of your camera, while the metal frame allows you to adjust the height accordingly.
