90mm wide angle Dagor f8, Flange Film/Focal Distance ?

[Morten]

Hi,

I have a guy which are looking to use said lens (Goerz Wide angle Dagor of 3 5/8” focus or 92.1mm f8) on one of 3d printed WillTravel 4x5 camera. As the camera body is rigid we need to establish the Flange focal distance to +/- few mm as there is some tolerance in the focusing setup.

Been trawling the forum and rest of the internet, so far no luck. Any information would be helpful.

Best Regards
Morten

I have no official information for you, but I do have one of these lenses and I measured the distance to the ground glass for my lens at infinity as 91mm or 3.583”. It would seem that they varied a bit in focal length and back focus and you will have to determine the distance for your lens at the distance you need. Good luck!
