After being seduced by full frame a few years ago (my beloved 5D), I'm now looking at trying my hand at medium format. This has mainly come about because I want high quality pics of some furniture I've built, and I only recently discovered the advantages that MF has in terms of lack of distortion compared with 35mm.

My current thinking (trying to get maximum bang for buck) is to acquire a Mamiya RB or RZ67 with a 50mm lens. I'd be happy to hear any thoughts about the camera choice, as well as anything related, ie is 120 film likely to be around for a while? Is there a reason there are hardly any recent posts on this forum about medium format?
