B4 lense issue after 4.5 camera update - Ursa Mini Pro

PostTue Nov 14, 2017 4:50 pm

After the 4.5 camera update to my UMP4.6k the b4 lens auto iris function no longer works. Auto exposure forces the lense to an F1.8 every time no matter if its in 1x or 2x extender. It also has an issue when powering. The lens is forced to a F18 even when the lens is in MANUEL at the zoom module. Anyone else using B4 lenses expierencing something similar?

Yes, I've noticed that, too. As a point of reference, this is the lens I'm using: Fujinon XA20sx8.5BERM-K3
