Sony Alpha a7R II 2015
Pioneering a 42.4MP back-illuminated full-frame sensor and BIONZ X processor, it delivers high-resolution stills and internal UHD 4K video with S-Log2, stabilized by 5-axis IBIS with up to 5 stops of correction. A weather-sealed magnesium body, 399-point phase-detect AF with Eye AF, and a silent shutter mode add versatility for discreet, all-condition shooting. It’s best for landscape photographers and hybrid shooters who need top-tier resolution and 4K log video in a mirrorless form factor, but not fast action or wedding events.
このCameraについて
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.
