摘要：
A reverse Galilean finder in which a front frame, preferably associated with a front element is projected away from the eye by the finder optics without separate frame projection optics to a position such that the distance between the apparent position of the frame to the eye and the rear vertex of the finder divided by the length of the finder is at least 2.2.
