Blackmagic Design today introduced the Blackmagic URSA Mini B4 Mount which is a B4 lens mount modification for its new Blackmagic URSA Mini PL camera that lets it use broadcast HD lenses. The Blackmagic URSA Mini B4 Mount is designed to replace the existing PL lens mount on Blackmagic URSA Mini PL, turning it into a B4 camera for HD. To install the B4 mount, simply take the PL lens mount off where it is normally removed for shimming PL lenses and bolt on the B4 lens mount.
Once the mount is installed, B4 lenses can be attached to the camera. Blackmagic URSA Mini PL also includes a new lens control connection that works with both PL and B4 lenses. This new connection supports both analog and digital lens control standards and also provides iris control and power for the lens.
The Blackmagic URSA Mini B4 Mount is a true lens mount replacement that features precision glass optics specifically designed to match Blackmagic URSA Mini’s sensor with high definition broadcast B4 lenses. The B4 mount also features spherical aberration correction so customers can use their lenses wide open with no blooming effect. The Blackmagic URSA Mini B4 Mount can be used with both 4K and 4.6K PL models of URSA Mini.
The built in PL lens mount on URSA Mini PL can be changed to the B4 lens mount whenever needed, letting you switch back and forth between B4 and PL at any time.
The Blackmagic URSA Mini B4 Mount will be available in November for US$295.
