IB/E PLx2 Extender for a wide range of PL-Mount Lenses
IB/E Optics PLx2 Optical Extender - for spherical and anamorphic PL Mount Lenses. The PLx2 optical extender doubles the focal length of 35 mm PL mount lenses. While most extenders can only physically fit on a limited range of lenses, the design of the PLx2 allows it to work with a wider array of PL mount lenses than any other doubler. The PLx2 features high-index, low-dispersion glass to ensure the highest possible resolution and contrast with minimal optical degradation. In magnifying the image twofold, the transmitted light is spread over a larger 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.
