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.
The HDx Optical Adapter turns the B4 lens into a longer focal length lens, so that the relative depth of field expected for the larger sensor is achieved, while the usual field of view when the lens is mounted to a 2/3”
camera is maintained.
All HDx Optical Adapters also 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.
