Hi,

I have an issue with my CLM-4 motor. It spins very quickly when doing its focus range from minimum to infinity, then keeps spinning endlessly. I tried the motor with another WCU-4 and UMC-4, and it did the same thing.

If anyone has experienced this and can give me advice, it would be appreciated.

Thank you!

Dear Helmi,

how can it spin indefinitely, when there should be hard stops on your lens? You cannot use the system with photo lenses that are decoupled from the focus-ring (because of the internal autofocus motors; Canon EF lenses for example).
Can you share a photo of your setup?

Thanks,
Jan
