This Nisha Eye Piece with Rubber Cup is a rubber eye cup with protective glass for select Sony DSLR cameras. The eye piece mounts onto your camera, and the rubber cup blocks unwanted light and provides added comfort while you are looking through the camera's viewfinder.
This accessory is compatible with most older cameras. Some of the more recent models released in 2011 and later are not fully compatible because the eye piece blocks the EVF sensor, preventing the automatic switching between EVF and LCD. This occurs with the Alpha a7, a7R, a7S, SLT-A65, SLT-A57, SLT-A58, SLT-A77, and a77II cameras.
