Is the image circle big enough for 16mm cameras? Could i adapt a newer b4 zoom lens to a vintage 16mm cinema camera?
Asked by: Andres
The image circle of the B4 mount lenses that the FotodioX B4 to C-Mount Pro Lens Mount Adapter works with are typically made to cover 2/3" sensors, which are smaller than the super 16mm format.
