The IB/E PLx 1.4 Mark II has improved optical performance especially at higher T-Stops. It extends the focal length of S35 PL mount lenses by a factor of 1.4, losing only one stop of light. The recommended max. input T-Stop is 1.6. The extender features high-index, low-dispersion glass to ensure the highest possible resolution and contrast with minimal optical degradation. The optical design is optimized for digital cameras with telecentric ray path at the sensor. Compatibility is achieved with a deep-set optical assembly that accepts lenses with deep protruding rear elements. The PLx1.4 Mark II is also designed to mount to 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, MFT or others without re-shimming.

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.

The IB/E Optics VVx2 UMS optical extender doubles the focal length of the RAPTOR macro lenses (*without 60mm Raptor). The VVx2 UMS features high-index, low-dispersion glass as well as multi layer coating 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 the RAPTOR macro lenses  and digital cameras, the maximum input T-Stop is 2.9. The VVx2 UMS is designed to mount to any digital cinema camera with a native PL mount. It will also clear the spinning mirror on any ARRI or Aaton camera. In addition the IB/E UMS Mount System offers the ability to change the mount to Sony E, Canon EF, and others in the field without re-shimming.
