I got deep enough into it to find a ground glass screen and a prism finder to slide onto it. Then I could set it up like a view camera, and when happy put on the film back instead and take the shot. But even then, the slightest error in aligning any vertical or horizontal line in the scene would screw things up. And my perverse desire to make it into a portrait camera (possibly one of my more stupid ideas, or just a really good challenge!) turned out to be well beyond my skill level. I do enjoy the 28mm lens on a 35mm camera, or the equivalent elsewhere, like the 20mm on my Pen-F or Distagon 50mm on the 503cx. But it took me some time to figure out how to use them, and I'm afraid I'm a bit formulaic in the way I do (subject close and to one side of the frame, rest of background as blurred as possible. You see why I like the Nikon 28mm/f1.4! I keep a 20mm/f2.8 around for the F6, and used to have a Voigtlander 15mm for the Leicas, but they were/are like fish-eye lenses, for rare special effects rather than regular use..
I think I made only a couple of semi-successful portraits with it (marred by clumsy processing of Delta 3200):

and one of my better half:
It was OK to set up a scene, but so hard for me to have something within that scene as subject:
Perhaps it would have all come together with a few dozen rolls of film until I caught on. But when it was suddenly time to (involuntarily, due to leukemia) rationalise the cameras, and I had to keep one medium format camera, there was no way it was going to be the SWC and nothing else. But I do love to see what other, more skilled people can do with it.
