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 good condition, there is hardly dust on it - but these will not affect the image as they are 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
