The translucent mirror in the Sony SLT A33-A77 cameras is quite delicate and easily damaged. This is a used mirror, removed from a 'dead' Sony A55 camera body. It is in very good condition, no visible dust spots, even if there were a few specs, they wouldn't affect the image significantly as the mirror is well out of the focal plane. If you haven't already damaged your mirror, why not buy one as a spare 'just in case'. Mirror comes in a protective case (made from a modified filter holder). Price includes 2nd class postage
