Guys, I'm about to order a Shen Hao and I am thinking about getting a Nikon 90mm f8 for landscape with it. I understood that normally for 4x5 it is best to use a recessed lens panel for wide angle lenses (including the 90mm), to allow for some movements to stay available. However, I will also be using the 6x17 panoramic back. This back sets the film plane back with almost 2" I believe. Does this mean that the lens needs to be even further back to keep infinite focus? How about the movements available? Do I still need a recessed panel with a 6x17 back? Will I have full movement with the recessed panel and the back, or will I be limited?
