Loosely turn the five mounting screws until initial
contact is made with the shoulder of the lens mount.
Using the 2mm Hex driver, or torque wrench with
2mm Hex key, apply one full turn of pressure to
mounting screw 1, followed by one full turn to
screw 2. Repeat for screws 3and 4, then 5.
Continue to apply one full turn to each screw in
the sequence above until all screws have reached
the maximum torque of 0.45Nm.
NOTE When removing the B4 mount, simply follow the instructions in reverse order
from step 4 to step 1.
TIP When using a B4 lens with URSA Mini Pro 4.6K, set the resolution to 2K 16:9 or
lower, and 'window sensor' to 'on' in the 'record' tab of the dashboard. It is important
touse these settings to prevent vignetting of the image, as B4 lenses do not cover
thesuper 35mm image circle. Once you have attached a B4 lens to your camera
andadjusted the settings on your camera, you should also check the back focus on
thelens.
