I was wondering if anyone had information on using this lens for 7 x 17 or larger ULF sizes. I checked the Badger Graphic Sales site and it shows it has an image circle at 485mm at f-22. I read that 7 x 17 requires an image circle of about 466mm, which means the lens will cover with minimal movement. I know that stopping down throws a larger image circle and was looking to see if this lens would be a viable option at f-64+ for 7 x 17 to allow generous movement of the front (lens) standard. I want to be able to have a bright image and this lens stops down to f-128, which is good if I need it compared to other similar plasmat lenses in this range.
