Converter

The HDx1.4 converts B4 mount video lenses for use with single sensor (S16 or 2K) while slightly correcting the image.  The HDx1.4 can be used with the following cameras with only one stop of light loss (1080p): Phantom Flex 4K Sony F5 / F55 2K Sony F700 Blackmagic Pocket  

The IB/E HDx35 Mark III is a high-end optical converter engineered to seamlessly adapt B4 mount 2/3” broadcast lenses for use on modern Super 35 large sensor cameras. Designed for demanding professional workflows, this converter enables cinematographers and broadcasters to continue leveraging high-performance HD ENG and box lenses in contemporary digital cinema environments. At its core, the HDx35 Mark III addresses the fundamental optical mismatch between traditional three-chip prism-based B4 lenses and single-sensor large format cameras. Through precise spectral correction and a highly telecentric optical design, it ensures accurate color reproduction, consistent illumination, and edge-to-edge sharpness across the entire image field. The Mark III generation expands image coverage and compatibility, making it suitable for a wider range of cameras including ARRI Alexa series, RED Epic systems, Sony CineAlta cameras, and more. With a magnification factor of 2.6x, it effectively adapts the image circle while maintaining strong optical integrity even at fast apertures. A key differentiator is IB/E’s Universal Mount System (UMS), allowing flexible adaptation to multiple camera mounts such as PL, EF, E, F, FZ, and Micro Four Thirds. Mount changes can be performed in the field without re-shimming, significantly improving operational efficiency in dynamic production environments. Handcrafted in Germany, the HDx35 Mark III reflects precision engineering and strict quality control standards. Its compact form factor, robust construction, and optimized coatings for flare reduction make it a reliable tool for high-end broadcast, live production, and cinema applications.

  IB/E Velociter x0.8 Optical ConverterThe Velociter x0.8 optical converter reduces the focal length of the RAPTOR macro lenses by 0.8x. At the same time it increases the lens speed by almost 1 stop. For example, the RAPTOR 100 mm T2.9 becomes a 80 mm T2.3. The Velociter x0.8 features high-index, low-dispersion glass as well as multi layer coating to ensure the highest possible resolution and contrast with minimal optical degradation. To create an optical design that is optimized for the RAPTOR macro lens family and digital cameras, the maximum input T-Stop is 2.9. The Velociter x0.8 can easily be assembled in exchange of the extension tube of the PL UMS mount. Note: With the Velociter connected to the lens, only PL cameras can be used. Not Compatible with Raptor 60mm. Technical data Max. image diameter (mm) 36.0 Magnification x0.8 Max. input T-Stop 2.9 Light drop (stops) 1.0 Diameter (mm) 54.0 Length (mm) 31.0 Weight (kg) 0.18  

The HDx2 Mark II was specifically designed to give cinematographers the ability to use all HD ENG 3D CCD lenses on high speed Phantom cameras and MFT format cameras (22 mm). This converter is best suited for scenarios when our HDx35 Mark III adapter‘s magnification is too strong or when light loss has to be restricted.
