“Medium format cameras come in a wide variety of shapes and styles, creating different methods to pull focus.
Twin Lens Reflex cameras (TLRs) most often have a wasit-level viewfinder, allowing you to hold the camera lower and look down to compose your image. The twin lenses allow for a mechanically simplified method of splitting light to the mirror as well as the film. Here we see two ways this can look in both a simple, less descriptive way, and a much clearer, more expensive fashion.
Other, more complex studio cameras, like this Mamiya RB67, are Single Lens Relex cameras (SLRs) and require the movement of an internal mirror to direct light between the viewfinder and the film. This Mamiya focuses by adjusting a the lens forward and back with a bellows system.” - Carlo
