The Wista 45N is the basic (or stripped-down) model in the series. It has manual rise/fall, shift and tilt on the front, and swing on the rear. The bellows are not interchangeable, and maximum extension is ~300mm. The monocular reflex viewer is attached in place of the focusing hood, and can be swung away when you want to use a loupe for critical focus. Since the viewer is attached to the back, it rotates along with it. For vertical shots, you'd need to stand to the side.
