Quick question. Can the sport finder wires to be raised while using a 90mm lens on a crown graphic. They can't with my Speed since the lens is within the body when focused. I believe I read that the lack of the rear curtain makes Crowns makes the body a bit thinner, but is it enough to get the front standard outside the body with a 90?

maybe on my Crown from the film plane to the lens board were you can still use the wire
sport finder is about 77mm SO with a Angulon 6.8/90mm the Back Focal Length (S'F')
84.7mm SO its should work
BUT Super-Angulon 8/90mm Back Focal Length (S'F')66.3mm MAY NOT

Both my 90mm f6.8 Angulon and my 90mm f6.8 Grandagon will focus at infinity with the wire frame up. I've not tried my 90mm f5.6 Super Angulon. I should add the sports finder frame just touches the body.
