The HDx2 Mark II is an optical adapter that enables B4-mount 2/3” HD video lenses to work with PL or Canon EF options to be compatible with such cameras as Canon DSLR, Canon C300EF and PL, Blackmagic camera up to PMW-F3, PMW-F5/ PMW-F55, RED EPIC and Alexa.  Supplied paired with Universal Mount System (UMS) (EF Option only).

Broadcast lenses are available in high zoom ratios with wide apertures in a relatively compact size, making them a desired option for many large-sensor camera users. Designed and built by IB/E Optics for AbelCine, HDx Optical Adapters mount between a B4-mount 2/3” lens and a large sensor camera, expanding the projected light to cover the image area.

HDx Optical Adapters increase the focal length of the attached video lens so that the expected field-of-view of the lens is maintained on the larger format sensor. The depth of field of the image will be closer to that of the larger format.

All HDx Optical Adapters optically correct for the different spectral alignments between three-chip prism block sensors, for which the B4-mount lenses were designed, and the single sensor of the large sensor cameras. HDx Optical Adapters are highly telecentric in design, delivering a bright, sharp image across the entire frame, with excellent color and contrast.

The HDx2 mk II adapts from B4 to a Universal Mount System, which allows the HDx2 mk II to be mounted on a wide variety of large-sensor cameras without shop service. It ships standard in ARRI PL, with available adapter mount options including Canon EF, Nikon F, Sony E, and Micro Four-Thirds. The Mark II includes a 3/8-16 threaded hole and two posts for lens support.

The HDx2 mk II expands a B4-mount lens image by approximately 2.2 times, covering:
