>>2624923I absolutely adore my Mamiya C3 and 80mm lens.
However I'm not sure it fills your "geometry" criteria, TLR's tend to have very simple optical formula combined with an extremely long focussing throw. This is not ideal for avoiding distortion. Not to say this can't be quickly and very effectively remedied in photoshop (simple lens design = simple distortion)
Despite the above and parallax error, it's definitely my most fun and enjoyable shooting experience. Perfect blend of usability and manual operation fiddly goodness.
Photo attached is the closest ive got to architectural stuff on it though.
