This folding side-bracket with foam grip is designed to serve as an additional mount for flash triggers, flashguns, mics and other accessories, and serves as an additional grip to aid in steadying the camera (when shooting video, for example).
The grip folds down for tidy storage and is manufactured from anodised aluminium, to keep the weight down.
This model features an Arca-Swiss style clamp, which will require a suitable Arca-Swiss style plate (not included).
