Mount B4 lenses to your URSA Mini camera with this adapter from Blackmagic Design.

This interchangeable B4 mount is designed exclusively for Blackmagic URSA Mini cameras with a PL mount. Precision correction optics adapt the B4 lens to the sensor and provide an HD image circle.
The mount replaces the existing PL mount and compensates for spherical aberrations associated with the design of B4 lenses for three-chip cameras. It expands their image circle to cover the Full HD sensor crop.
Connecting the lens to the broadcast lens controller port activates the servo. BMD specifies use with the URSA Mini 4K PL and 4.6K PL; this is not an accessory for the URSA Cine nor a universal B4 adapter.
