Vidéo optimisée, sensibilité optimisée, vitesse optimisée, le Sony a7S III élève
la barre de ce dont un appareil photo sans miroir plein format est
capable. Un capteur CMOS Exmor R BSI 12,1 MP révisé et un processeur
d'image BIONZ XR mis à jour offrent des performances plus rapides, une
réduction du bruit améliorée et une plage dynamique plus large, ainsi
qu'une vidéo UHD 4K 120p.
