Sony Alpha a7R II 2015
{"review": "Le capteur plein format 42,4MP Exmor R rétroéclairé et le processeur BIONZ X offrent des images haute résolution et un enregistrement 4K interne avec S-Log2, le tout dans un boîtier tropicalisé. Sa stabilisation IBIS 5 axes compensant jusqu'à 5 stops et son viseur OLED de 2,4 millions de points facilitent la prise de vue à main levée en photo comme en vidéo. Ce boîtier d'occasion est idéal pour les débutants motivés et les créateurs YouTube exigeant une qualité d'image 42MP et une captation 4K sans recadrage."}
À propos de ce Camera
With a world's first full-frame 42.4-megapixel Exmor R back-illuminated structure CMOS sensor, the Alpha a7R II Mirrorless Digital Camera from Sony is prepared to take mirrorless imaging to another level. This sensor design both improves low-light operation and speeds up data throughout, enabling fast high-resolution stills and UHD 4K video recording. Working with the BIONZ X image processor, these images can be produced at sensitivities up to ISO 102,400 and at a continuous 5 fps shooting rate. Five-axis SteadyShot INSIDE image stabilization has also been implemented, compensating for vertical, horizontal, pitch, yaw, and roll movements.
