I currently have a Mamiya 645 and I would like to step up to an outfit with a larger frame size, like 6 x 7. I am not a big fan of square format due to the cropping issues. The equipment will be used to shoot mostly portraits and weddings. I have been looking into the Mamiya RZ67 and the Pentax 67 due to ther flexibility and reasonable price range. Also, I plan to get a poloroid back for whatever system I buy. Any thoughts or suggestions?
