Australian distributor is hopeless. This is the reply from Libec USA.
These guys have awesome controllers but nothing that works with the ex3 for now. This is a reply from them
“At this time we do not have a zoon controller that will work with the PMW-EX3 camera. Our engineers are working really hard to trying to make the necessary changes to Have one available as soon as possible,
Please check our web site https://www . libecsales . com periodically since we will announce it as soon as we have Have it available.”
I think it is the Job of the Distributors to notify the re-sellers.
I still have not bought a new controller. Thinking about going manfrotto.
