The question I would ask myself is, do I need another camera, will it improve my photography ? what will it do for me that my existing equipment will not for the type of work that I do, do I need it or just want it ? If I had a Bronica S2A outfit I wouldn't buy a Mamiya outfit, although I have used the Mamiya TLR system for more than twenty years, I would think the Nikkor lenses in particular for the S2a are better than the mamiya lenses, and the Zenzanons are at least as good.
