Sure. You can use IBIS, just set lens info in the stabilization menu to 35mm. My videos were all handheld, so IBIS was effective.
It's all manual, of course. The big challenge was focus. The lens barrel has distance markings, the focusing mechanism is long throw and linear, which is all good. The magnification button of the fx30 is really helpful as are the colored focusing aid (I chose red). I didn't try the new full screen color mapping for focus.
Occasionally I would forget I needed to focus, I have relied so much on Sony's auto focus. It does slow you down. I was conservative in not choosing the widest apertures because I didn't want a shallow dof in case I misfocus. Using wider apertures in some shots would have been nicer for image quality. Also wider apertures make what is not in focus more evident.
In DaVinci Resolve desqueezing is easy: just select all clips, right click for clip attributes, and choose the pixel aspect ratio as 1.33X. This perfectly desqueezes this 1.33X anamorphic lens clips.
I shot without a monitor to desqueeze. I have no problem composing shots as the lcd shows exactly what is in the frame, just squeezed. I was pleased with the compositions. I have shot anamorphic before without a desqueezing aid.
