The point of one camera, one lens, one film (and one developer) is to eliminate as many variables as possible so the beginner can concentrate on the work at hand, learning to make pictures with a camera whether that camera is an 8x10 Deardorff or a Kodak 35.
When you are utterly familiar with the equipment and can use it intuitively (as Thomas pointed out) to get exactly the technical performance you need, then and only then can you begin to learn to "see". A Maslow's hierarchy of learning, if you will.
