I assume you are referring to the differences between monorail cameras and folding baseboard cameras *keeping the format constant*. I think the major benefit of a monorail camera is the great range of adjustments (swing and tilt). At the same format, a folding baseboard camera may be more limited. OTOH, I think it is virtually impossible to shoot w/o a tripod with a monorail camera whereas it is possible with a folding baseboard camera. (I sucessfully tried that with an old 9x12 cm plate camera a few times. 4x5 inches should be equivalent.) As for ease of handling, I think the folding baseboard camera wins hands down.(posted 8970 days ago)
