Interesting comments so far. I'm a little surprised by the number of recommendations for 6x6 TLR's. Although I'm aware that Imogen Cunningham used Rolleiflexes for portraits (and I greatly admire her photographs,) I hadn't thought it to be really all that great of a portrait camera. Maybe I should re-think that. Similarly, I'm also thinking of large format possibilities such as Graphics and Graphlexes and maybe one of the newer Polaroid camera conversions, with a Graphlex back. My aging back would appreciate something a little lighter though, I think. I have a great 35mm Minolta Maxxum camera but I think it's too loud for this task, too stereotypically "smile, camera in use!". If I go 35mm a rangefinder would be preferable because it's very quiet. I love my Yashica Electro but the 45mm lens is really shorter than I think I'd like for this sort of thing. My impression, though, is that a Leica with a couple of lenses would be out of my price range. I need to come in at less than $1000, preferably a lot less. Thanks for all the great ideas, everyone!
The more I think about it, the more I like the idea of using a Rolleiflex. Hmm. Using FP4 or TMX, it wouldn't hurt a bit to crop 30% or so of the negative, if necessary. Hmmm, again...
