Lens control features are not a new thing. However, most of the issues ive seen arent like mine, or seem to be a different scenario.
Im using a Broadcast 4ME switcher, a Color Control Hardware Panel, and the large Broadcast control panel. We are on Ursa Mini 4.6k CF and PL Mount. I own two 40x B4 2/3" lenses. As you can see, these are are not cheap in anyway!($82k). These are attached to both a URSA MINI 4.6k and a URSA Broadcast. Both experience the same problem.

1) Talley works flawless
2) IS on lens works Flawless
3) Camera Control, Iso/Shutter work flawless.
Focus and Zoom are done manually by the operator
Whats NOT WORKING is the Iris! The servo can be set to Auto or Manual. I can get camera control Iris to work perfectly, and then when it's show time, it suddenly quits working and i cant get control back. Even though everything above works, only the Iris control fails. Sometimes I power cycle the camera, or remount the lens, or connect and reconnect the lens control connector from the body of the Ursa. I have been unsuccessful to what specifically is creating the issue or what fixes it. Its very inconsistant.
This problem is repeated with both URSA Mini 4.6k and the URSA Broadcast using the HJ 40x lenses.
Inspection of the pins show nothing weird. I am using a single shim (The thinnest of them) but beyond that, Im not using any shims.
Any help would be greatly appreciated
