A technorama is quite a different beast altogether, it's a technical camera and mostly intended for slow tripod work - much harder to focus and shoot handheld like you can with a 7.

If that sort of thing interests you, you might want to consider a 4x5 field camera with a 6x12 back; though that's even more-extreme on the slow/considered spectrum of shooting style, it gives you more movements (perspective and focal-plane control).
