So I have a few different cameras and I want to consolidate into one solid system. I don't have a lot of money so I would be looking to trade off for lenses etc for the remaining system. I just need advice on what to keep. For medium format, I have a Rolleicord III, Agfa Isolette, Bronica SQ-Ai w/ 80mm PS f/2.8 and non-metering prism, and finally a Mamiya 645 w/ metering prism and 150mm f/3.5 lens. I'm definitely keeping the Rolleicord. But what I want to know is whether I should keep the Mamiya or the Bronica. I like the way the Mamiya feels, but it's limited in the format it shoots. With the Bronica I have inserts for the 6x4.5 format. So what do you think?
