The problem with the Rolleis and Hasselblads and all the rest, is that they are "look down into" cameras. And in the case of the Rolleicords, they are particularly dark, especially when the hot bright sun is overhead. You can't see ZILCH. Try that when taking people pictures especially. You look up to see if everybody has their eyes open, then you look down, only to discover you have to re-position. So you look up again, then down. At one point you decide to just go ahead and shoot. And hope. So now you have a square negative. But all the paper sizes are rectangular. So you crop. Now you've got a 645 negative, at best. Not a fun camera at all. Not to mention that the Germans saw fit to lock the f/stop dial and shutter speed together. so that is fiddly, slow, and annoying. Did I mention how dadgum dark it is looking down into that thing?
