There's really no single best camera in general- that's a subjective question. For architecture you can go several ways. A 35mm SLR may be used with a PC (perspective control) lens that allows you to prevent distortion that would otherwise occur when your camera is angled such that the film plane is not parallel with the plane of your subject i.e. a wall or beam. The best quality result for this type of photography is probably best with a view camera that is set up on a rail that allows perspective control such that the film plane position is adjustable independently of the lens position.(posted 9139 days ago)
