The LPLx2 VV Optical Extender doubles the focal length of Vista Vision Format LPL mount lenses. Its compact optical and mechanical design makes it compatible with a wide range of lenses. High-index, low-dispersion glass ensures the highest possible resolution and contrast with minimal optical degradation. The extender transmits light over four times the area with a decrease in brightness by two f-stops and has a recommended maximum input T-stop of 1.9. The LPLx2 VV mounts directly to native LPL mount lenses and cameras.
