The Toyo 45CF is advertised to have a minimum bellows extension of 80.3 mm. I have an f5.6 75 mm Super-Angulon lens with an advertised flange local length of 82.8 mm. If both of these numbers are correct, I should be able to focus this lens at infinity with a few mm of movement. I measured the flange focal length of the lens and obtained a number a little larger than 82.8 mm. Do any of you know the accuracy of the 80.3 mm number? Have any of you used this lens on the Toyo 45CF?
