The B4 Mount Blackmagic for URSA is installed on the front of the camera, replacing the factory holder, thanks to this accessory it is possible to place any optic compatible with B4 technology.
the URSA Mini Pro B4 mount from Blackmagic Design is a spare mount for use in the URSA Mini Pro. This mount allows you to use your ENG-style B4 mounted HD lens on your URSA Mini Pro. The mount incorporates corrective optics that allow the use of a lens designed to work in a camera with three sensors and a prism, in the URSA Mini Pro, which is a single-sensor camera, without the image suffering optical degradation.
The lens mount accepts lenses with a B4 lens mount and features a locking lever to activate the mount lock. The included lain kit allows precise adjustment of the flange distance when installing this bracket on your camera.
The integrated optics support HD resolution and is designed with spherical aberration correction that compensates for lens use in a single-sensor camera, while it is designed for a prism/three-sensor block camera.
