A: The DJI RS 2 Gimbal Stabilizer can work with most lenses. The support weight is part of the concern. The Panasonic Lumix S PRO 16-35mm f/4 Lens is around 1.1 lbs and the gimbal can support up to 10 lbs. It will work but note, that when you zoom the lens you will need to balance the gimbal each time. Most use prime lenses when using a gimbal or do not zoom the lens.

Q: 10. Is there a tripod mount for this lens? How to support this on a tripod to relieve the stress of its weight on the camera lens mount? Just letting it hang off the camera, with only the camera body attached to the tripod would seem to weaken the lens mount, especially over time.

A: There is currently no lens support available for the Panasonic Lumix S Pro 50mm f/1.4 lens. While the concern is understandable, there have been no recent reports of such issues happening and such an occurrence is not common today due to more robust mount-engineering practices.
