Watson VM-CLAMP Reviews

Barely fits onto 35mm leg

By Eric
Rated 4 out of 5
Date: 2026-03-13

The specs say it fits 36 mm diameter, and another reviewer says 1.5” (38 mm). I bought it for a Manfrotto 475B which has a 35 mm leg diameter. I have to force it onto the tube, and it barely fits. I would recommend for 32 mm or smaller. Other than that – it is well-made and sturdy.

Works well

Don't have tons of experience with these batteries yet but with my 50wh v mount battery it held it in place well and let me fix it to fairly thick neck of my tripod so I could run power through dummy battery on my camera. If you need this kind of solution it works well...fells well made and holds in place firmly

Is the clamp wide enough to attach to a Zhiyun Crane 2 body?
Asked by: Roy
As the base of the Zhiyun Crane 2 is wider than this clamp can support (up to 1.4"), this would not be recommended. An accessory that would mount to the base of the Crane 2 is a Zhiyun-Tech Extension Mounting Ring for Crane-2 (SKU: ZHGMBC531). This could be then attached to a v-lock assembly such as the Smallrig 1846 V-Lock Assembly (SKU: SM1846B).

Is it possible to separate the clamp from the V-Mount release? How is the V-Mount release connected to the clamp?

This has screws holding the V-mount in place. We do not recommend removing them though.
