My first serious medium format camera was the C220 with 3 lenses. I still have it and use it occasionally though my wife uses it more. What I remember at the time was that, at a convention I went to annually, there was a group portrait concession at the hotel that used C330's handheld with a grip attachment and a flash mounted on the shoe the grip had. If you fold down the center of the front of the gg hood and sight through the little square hole in the back of the hood, you have the "sportfinder"....kinda like using a speed graphic with the metal tube framing square on top. The results were excellent enough for their business of selling portraits and the photographers using them worked incredibly fast. As a street camera, the Mamiyas can be made to work exceedingly well.
