The Zacuto 1/4 20" Lens Support is designed to fit onto a set of camera mounting rods. It clamps onto the rods, fitting underneath the lens to provide additional support. Once attached the unit screws into a Q-mount of your choice. This model comes equipped with clamps designed for 15mm lightweight rods.
Does what it needed to do. The SONY SELP 18110g lens seemed a little bit too heavy for the SONY FS5 M2. I needed a lens support and chose this Zacuto one to go with the Zacuto recoil shoulder rig. Sturdy piece of kit.
use it to support my 28-80 cine lens buyed it in august 2014 the thread screw did not stand it turn for ever and did not clamp the rod any more... not pro gear at all. realy thot this would last at least a year.... i also think this product is way over branded // i mean 5 logos on that...please...
