The M viewfinder frames correctly display the perspective of the lens in question, assuming the frames for that lens appear in the viewfinder. There is no way they could not do so without optical distortion. Assuming that you remain in one place, perspective is then a function of angle of view, which is a function of focal length of the lens used. If the viewfinder shows the field of view for the 28mm lens, it automatically shows the same perspective. Likewise the other frames in the viewfinder. You can experiment with a rectangle cut out of a piece of card to try different angles of view. It will all make sense in the end. ;-> -- joe b.
