Just to give an update to my original post. I’m glad to report that using the focus motor to zoom on the X-T3 and 16-80 lens works rather well.
My requirements were really just to be able to zoom between 50mm and 80mm and I balanced the camera at the midpoint of 65mm, however the Ronin SC seems quite comfortable zooming across the full range- not that I really expect to use it in that way.
A couple aspects I discovered were:
1. The Y support for the front of lens nestles in ok between the zoom and focus rings when balanced at 65mm, but ends up touching the zoom ring if I balance at 50mm. In that case I leave the support off. I do wonder if it really is even needed for this size lens amyway?
2. With the lens naturally not being parfocal, there are moments where focus can be lost when zooming while filming. Switching to manual focus and a high aperture to get a deep depth of field sorts that out though.
Overall though I’m very happy with the performance of the gimbal with the X-T3.
