I am trying to determine the correct focal length lens to purchase that would cover the groups that I photograph in my studio.
Using a Mamiya 645 with a P21+ back I need to purchase a 35,45, or 55mm lens. I would prefer the 55mm.
I looked at the metadata on some files that were shot with a 24 -70mm Canon lens mounted on a 5d, and found the widest focal length that I have used is 51mm. Most of the group shots were 54-60 mm.
