When movements (especially lens rise) are needed on the road, my favorite combination is a Toyo 4x5 field camera with roll-film backs (6x9 and 6x12). The carbon-fiber camera is not heavy, and the two backs give me a choice of film, or at least film size, and do not need a darkroom or changing bag. I have some nice transparencies from Spain, mostly architecture, where the motions (and tripod) were necessary.
