Many professional medium-format cameras are [[system camera]]s, which means that they have various interchangeable parts. Like most 35&nbsp;mm [[single-lens reflex camera|SLRs]], these cameras usually support different [[photographic lens|lenses]], but in addition it is also standard for medium-format system cameras to support different winding mechanisms, [[viewfinder]]s, and camera backs. This flexibility is one of the primary advantages of medium-format photography.
