The Focal Length Extender from IBE OPTICS is designed to double the focal length of VistaVision Format PL mount lenses. It features high-index, low-dispersion glass for high resolution and contrast with minimal optical degradation. In doubling the image size, the transmitted light is spread over four times the area, decreasing the brightness by two f-stops. To create an optical design that is optimized for modern lenses and digital cameras, the maximum input T-stop is 1.9.
The PLx2 VV is designed to mount on any digital cinema camera with a native PL mount. The UMS Mount System makes it easy to change the mount to Canon EF, Sony E, or others without re-shimming.
