As you guys know, I've been on a hunt for a medium format camera. I had the chance to play with an old Rolleiflex (3.5 Planar I think) a few days ago, and wow, I got the TLR bug. It feels like one of the perfect street photography cameras due to the combination of a waist-level finder and separate viewing lens. I think people take vintage cameras like a Rollei less seriously and don't realize that when you're looking down and fiddling with it you could be taking their picture. I think they think you're trying to figure out how to work the thing! Anyway, I was thinking about getting maybe a 2.8, either Planar or Xenotar, and an average meter to wear around my neck. I've heard they provide some of the best optics/image quality, and from my short chance to play with one, they feel like a pleasure to use. Any recommendations? Experiences? More information? I'm thinking about getting one from KEH in BGN condition.
