The HDx35 is an optical doubler that enables B4 mount 2/3“ HD video lenses to work with most 35 mm format large sensor cameras, the Mark II system has increased coverage to work with more cameras. Available mount options include Canon EF, Nikon F, Sony E and Micro Four Thirds as well as the ARRI PL mount.Add to kit list
The HDx35 Mark II adapts from B4 fitting to a new Universal Mount System.
HDx optical adaptors are mounted between B4 mount 2/3” HD lenses and the newest super 35 cameras and will cover all (4K) image areas.The adaptor turns the B4 lens into a 2.6x longer focal length lens in which 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 Adaptors 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 Adaptors are highly telecentric in design, delivering a bright, sharp image across the entire frame, with excellent colour and contrast.
