Comes with its own viewfinder (for framing only, you still need to use the scale markings for focus. Early French zoom lens designed in the late 1950s. Optics that go to the camera are clean. However, there is fungus in the viewfinder that will effect what you see while framing. Does not effect picture being photographed. You will need a bolex locking screw to keep your turret from turning as this is a heavy lens. Case NOT included.
