With a world's first full-frame 42.4-megapixel Exmor R back-illuminated structure CMOS sensor, the Alpha a7RII 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 PAL 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. Speed has received a major boost with a 40% increase in speed over its predecessor. The AF system received its own massive upgrade with the use of 399 phase-detect points and 25 contrast-detect points for a speedy Fast Hybrid AF system which will offer extremely accurate tracking. The phase-detection points even extend to A-mount lenses when used with the LA-EA1 and LA-EA3 adapter. Designed to last, the updated magnesium alloy body has improved weather sealing and a robust lens mount for working with large lenses. Also, the shutter has a reduced- vibration design, cutting down shutter vibrations by about 50%. Also, it now uses an electronic front curtain shutter and is rated for 500,000 cycles. Silent shooting is also available for a quiet shooting experience when needed. Onto video, the major addition is internal UHD 4K 3840 x 2160p recording at 30 or 24 fps with the XAVC S format at 100 Mbps. This is possible using either the Super 35 crop mode, with no pixel binning, or the full-frame readout. Full HD 1920 x 1080p is still readily available at up to 60 fps and HD 1280 x 720p is possible at up to 120 fps. Additionally, the a7RII benefits from the inclusion of the S-Log2 Gamma and S-Gamut settings as well as fully customizable picture profiles. Composing and reviewing your images as you work is handled with either the 0.5inch 2.36M-dot XGA OLED Tru-Finder electronic viewfinder or the 3.0inch 1,228.8k-dot tilting LCD monitor. The viewfinder offers 0.78x magnification and a 4-lens system with double-sided aspherical elements for comfortable viewing. The monitor helps in odd positions by tilting up 107° and down 41°. And, to stay connected, the a7RII packs in Wi-Fi connectivity with NFC for remote operation and transfer of images to a smartphone, tablet, or computer. 42.4 MP Exmor R BSI CMOS Sensor and BIONZ X Image Processor The world's first back-illuminated full-frame sensor, the 42.4-megapixel Exmor R CMOS sensor present in the a7RII works with the BIONZ X image processor to offer high-resolution stills and video while minimizing noise and improving speed. This sensor structure works with gapless on-chip lens design and an anti-reflection coating, as well as eliminating the optical low-pass filter, to improve light collection and enhance detail. Also, the copper wiring layer dramatically improves data transmission speed for creating high-resolution 42.4-megapixel stills at sensitivities up to ISO 102,400. Also, it enables internal UHD 4K video recording with a wide dynamic range using the full-frame sensor. 5-Axis SteadyShot INSIDE Image Stabilization Packed into the svelte a7RII is a 5-axis SteadyShot INSIDE image stabilization system. This compensates for five types of camera shake encountered during handheld shooting of still images and video. This allows users to confidently use any lens, even adapted lenses, for critical imaging without encountering blur from camera shake. This system will compensate for approximately 4.5 stops of shutter speed for working with a huge variety of subjects. For long focal lengths, the system will correct for pitch and yaw adjustments. Macro and high magnification imagery on the other hand will benefit from the inclusion of horizontal and vertical shift compensation. And, all shooting styles will get usage out of
