Ce que disent les acheteurs
Canon RF 28-70mm f/2.8 IS STM
90 sur 100 confiance moyenne 13 avis
L'objectif Canon RF 24-70 mm f/2,8L IS USM est très apprécié pour sa netteté, son autofocus rapide et son poids léger. Les utilisateurs le considèrent comme une excellente mise à niveau par rapport aux objectifs de kit, notamment pour les appareils hybrides comme le R7 et le R5 Mark II. Un seul avis négatif est lié à un problème de livraison, et non à la qualité de l'objectif.
