Review: better than sigma's original - honestly this is miles better than the original sigma included one and as its made out of metal it feels a lot sturdier. However the main issue would be the end stops I believe they are (small silver screws) they dont seem to serve a purpose on most tripods I've used as they are either too short when fully extended or too small to catch the latches. One useful point is that if your tripod supports rail mounting (without the base plate) then you can drop this straight on the tripod and tighten it to use making it more convent than having to buy multiple plates or swap the one that came with your tripod.
Review: Très bel article, léger, s'adaptant parfaitement à mon objectif 120-400 Sigma. La bague est très légère et permet de se fixer sur un trépied sans problème. La livraison est donc conforme à la commande, l'emballage double est parfait, le délais rapide.
