Sorry to go off topic of original post, but the question made me think of it and perhaps also not applicable to APUG. But wouldn't a 35mm size d*g*t*l with a shift lens of the correct focal length be able to take multiple shots of a static subject and join them up to give a large format equivalent?
Sigh... I suppose in the same way a synthesizer can be made to sound like a grand piano. It sounds fairly close to the average listener but is an entirely different experience for the musician.
