Sony a7R II Mirrorless Body

The α7R II has a 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.

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-step faster shutter speed, allowing you to take advantage of a wider range of shutter speeds.

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 S format allows 4K recording at 100 Mbps maximum bit rate to capture fine details of movement in movies.

The high-performance image sensor enhances Fast Hybrid AF, which far surpasses conventional AF in comprehensiveness, speed and response. The 399 focal plane phase-detection AF points cover 45% of the image area — the most coverage among digital still cameras with full-frame image sensors. 25-point contrast-detection AF coverage is also included.

The new shutter's braking mechanism cuts mechanical front/rear curtain vibration by about 50%. Also, use the electronic front curtain for even less vibration. This not only minimizes camera shake that can blur details in 42.4-megapixel images—it makes the shutter durable enough to have been tested to 500,0008 cycles.
