Serious photographers still use the Rolleiflex, and 120-size film is still available. You can still buy a brand new 2.8 model with superb multi-coated lenses and a modern built-in light meter.
Update June 2016: I have been using black and white film more and more and bought another Rolleiflex. Of course I should have not sold my earlier ones, typical dumb decision. Some first tests with Tri-X film in Vicksburg are here (click the link).
