So, I got this nice Nikkor-SW lens with a 4x5 Crown a while back. Seems sort of a waste to use this lens that can cover 5x7 on a 4x5 with no movements. I tried mounting it on my GV-II but couldn't focus the lens at any reasonable distance. And, even if I had, I suspect that large rear element would have hit the bellows if I tried for any movements. What do I need to do to make this lens usable (the only other LF camera I have is a 5x7 B&J)?
