Today I tested the new Zhiyun Crane 3S on the new Canon C300 Mark iii with the Canon CN-E 18-80 T4.4 and it handled it pretty well!
I used the Zacuto VCT Pro Tripod Dock to mount it to the Crane, and love how quick you can go from a shoulder rig, to a gimbal setup. Zacuto makes some rock solid camera accessories, and I highly recommend them.
