New back-illuminated full-frame CMOS sensor
The α7R II has the world’s first1 35mm full-frame CMOS image sensor with back-illuminated structure, which achieves approx. 42.4 effective megapixel resolution, widely expanded sensitivity range2 and extra-low noise performance. It also has no optical low-pass filter that can compromise sharpness, so fine clarity and detail extend from edge to edge of every frame.
High-speed BIONZ XTM image processing engine
With detail reproduction technology to capture the essence of realism, diffraction-reducing technology to maintain clarity even at smaller apertures, area-specific noise reduction to reduce noise adaptively and reproduce greater detail, the BIONZ X image processing engine finely tunes the image sensor's 42.4-megapixel data, for truer, clearer depiction.
Higher-resolution 4K movie recording
Footage from 4K movie recording featuring full pixel readout without pixel binning in the Super 35mm format exhibits higher resolution and superior clarity than typical 4K movies. Also, the XAVC S5 format allows 4K recording at 100 Mbps maximum bit rate to capture fine details of movement in movies.
5-axis image stabilization
This stabilization system is fine-tuned for high-resolution image sensors to compensate accurately for five types of camera shake that can compromise handheld shooting of the camera's 42.4-megapixel images. Camera shake compensation is equivalent to using a 4.5-step4 faster shutter speed, allowing you to take advantage of a wider range of shutter speeds.
