Review: Very useful and strong! - I purchased this to attach more bits and bobs to my camera such as external monitor, microphones, mobile holders etc and it works great for all that! Fits my Sony A7IV and A7III both. Has so many holes for different attachements and also hotshoe mounts on both sides. Very strong and adds a bit of weight, but not overly heavy. Highly recommend 🙌🏽
