Ursa Mini 4.6k EF - I can't change the Iris

Hey, I've not used an Ursa Mini in nearly a year and when I've just had a little refresh none of my Canon lens which are all common and I've previously tested compatible ones, are not showing the option to change the aperture.

It's value is blank on the flip out monitor and the Iris button and << / >> buttons are doing nothing.

I need to use it on a job tomorrow and can't figure out what's wrong.

I'm assuming it's something simple that's been changed.

Is the UM updated with the latest firmware? Take a look at this thread...

Very unlikely for it to be the same issue as that thread on an URSA Mini 4.6K.

Certainly download the latest Camera update from our support site and flash you URSA Mini with it.
