b4 lens compatibility?

Hey all, I have a Fujinon XA20sx8.5ERM-k3 lens and the camera does not seem to recognize iris control.

Am I missing a setting on the lens or is this lens just not compatible with the URSA 4k Broadcast cam?

scratch that -- recycled power on cam and it works.

Same lens on a job yesterday.. Power cycled a few times but it didn't butch..

My list of lenses we use with Ursa 6.7FW
- Canon Box UJ90x - works great
- Canon Box XJ86 - works great
- Fujinon Box UA107x - works great
- Canon HJ40 - works great

- Fujinon XA16, 17, 18 - works great
- Fujinon ZA12 - works great
- Fujinon ZA22 - It works, but after an hour of inactivity - the servo focus stops working.

- Canon HJ21 - It works, but after an hour of inactivity - the servo focus stops working.
- Canon HJ22- It works, but after an hour of inactivity - the servo focus stops working.
- Canon Canon hj14 - It works, but after an hour of inactivity - the servo focus stops working.
- Canon hj11 - It works, but after an hour of inactivity - the servo focus stops working.

- Fujinon XA20, fujinon ha22 - iris problem.

XA16 does not work, cannot set back focus

Interesting info Kim..
