I always thought that film was manufactured in huge sheets, then after
further ageing was sliced into strips, perforated, typed and batched.  Th=

whatsit" of 8 x 10.  This cropping would not be necessary if the image
extended to the film edge.  Therefore the effective increase in area woul=
be close to 30%.  Add Leica lenses to the equation and the result would
draw the MF folk, not to mention the rest of the 35mm world.

The competition would be forced to follow Leica's lead.  Or should I say
continue to follow ... =20
