I've been making the plunge into 4x5 and purchased a Chamonix 45-H1, and I like wide angle lately so I purchased a 90mm Fujinon 5.6 that is designed for 5x7. I would eventually like to buy the 5x7 back for the Chamonix so I felt that would be a great lens.

It is a quite physically large lens and when I move front standard the back of it definitely hits the "universal" bellows. My theory is that it doesn't really matter as that part of the image circle isn't used anyway. Is this correct? Or do I really need a bag bellows.

Also, I would love a suggestion on a great 90mm lens or close that is smaller mainly to have a lighter weight set up.
