Blackmagic URSA Mini Pro B4 Mount
With the B4 mount attached to your URSA Mini Pro 4.6K, you can mount par-focal zoom lenses
commonly used for electronic news gathering and wedding videos. These lenses maintain
focus throughout large zoom ranges and typically have manual focus and iris control, plus a
zoom rocker on the hand grip allowing you to smoothly ease in and out of the zoom. For single
operators, using these lenses makes shooting very fast and efficient with exceptional control
over the shot.

Tools Required
When attaching the B4 mount, you will need a 2mm Hex driver. While it’s not absolutely
required, we recommend using a torque wrench able to accurately set a maximum torque
of0.45Nm to reduce the potential of over tightening the screws.
