Hi all, My first APUG thread!.. I am currently using a Leica M7/35mm Summicron for street photography but I want a bigger neg. I want try a waist-level camera for discrete shooting so I'm not considering a Mamiya 7. In addition, I also want to use the same camera to experiment shooting 'tree-portraits' wide-open with a 'creamy' bokeh. Hence, a TLR seems a good option? I am willing to spend around US$1500. Is a Rolleiflex the way to go? Which version has the best optics? Does the lens vignette considerably? Any other cameras recommended? Thanks in advance.
