I think the adapter may need to talk to the camera via the lens which according to the manual would have a setting in the menu for MZ/PZ, manual zoom/power zoom. The manual talks about Canon EOS cameras and only mentions the EOS 80D, so you might be up against a compatibility issue.</P> Thu, 03 Apr 2025 21:03:07 GMT IamintheUK 2025-04-03T21:03:07Z https://community.usa.canon.com/t5/EF-RF-Lenses/Canon-EF-S-18-135mm-f3-5-5-6-IS-USM-with-Canon-PZ-E1-Power-Zoom/m-p/542677#M37224 <P><SPAN>I am using a Canon EF-S 18-135mm f3.5-5.6 IS USM with Canon PZ-E1 Power Zoom Adapter on a Blackmagic Design Ursa 12k mini pro Video Camera with a Manfrotto remote. Everything is working except the zoom. Any ideas why?</SPAN></P> Wed, 02 Apr 2025 07:45:10 GMT https://community.usa.canon.com/t5/EF-RF-Lenses/Canon-EF-S-18-135mm-f3-5-5-6-IS-USM-with-Canon-PZ-E1-Power-Zoom/m-p/542677#M37224 Nigel123 2025-04-02T07:45:10Z https://community.usa.canon.com/t5/EF-RF-Lenses/Canon-EF-S-18-135mm-f3-5-5-6-IS-USM-with-Canon-PZ-E1-Power-Zoom/m-p/542954#M37225 <P>Make sure the zoom lock is off.
