Here's my 2 cents. I've used the RB system for years, and have never been dissapointed with any of the Mamiya lenses. I do landscape, city buildings, studio, and in home portraits, and a little product work. I would probably suggest either the 65mm, or the 50mm lens. The 50 gives you approximately what you would get with a 28mm on a 35 film camera. I love it, as I am a true wide angle slut. Mamiya also made a 37mm(?) fish eye that I would love to own, but they are relatively rare, and when they do come up, the price is always waaay out of my range. The Rb is a big beast, and a tripod is almost always a must. As far as the WL finder goes, it does take a bit of getting used to, but it's a pretty minor thing. There is a eye level finder available too.
