I'm looking to purchase a 75mm wide for my Technika 2x3 and need to know the rear mount diameter of the 75mm Super Angulon 5.6 SC and MC. I think there is a slight difference in size and don't know if either will fit through the opening in the front standard of the Technika 2x3. Also would like to know the same dimension of the two models of 75mm Grandagon and the Nikkor W 75 4.5.
Thanks in advance!
Don
