I love the 6x9 negative that you get from the Mamiya - especially with the 65mm lens. It's built to take alot of abuse and is not all that heavy. I have three backs so I carry B&W, Colour Neg and Transparency film -it's easy to change from one film to another. But like others have mentioned before - make sure you get the finder for the 65 or 50mm lens
