The film gate, combined with the angle of incidence of light determines the
negative shape. When the rear element of the lens is VERY close to the film
plane, the incident light to the edges is at such an angle as to project
under the edge of the gate. With the SA the image area on the negatives
have nearly no space between them. The first time I saw this I was sure
that there was something wrong with my camera until I figured out what was
happening.
