Sony Alpha 7R II With 42.4-Megapixel Back-Illuminated Full-Frame Sensor Launched in India
Sony India has announced the launch of its new flagship full-frame mirrorless camera, the Alpha 7R II. The Sony Alpha 7R II interchangeable lens camera features a back-illuminated full-frame Exmor R CMOS sensor with a resolution of 42.4 effective megapixels and ISO up to 102400.
The Alpha 7R II also includes a 5-axis image stabilisation system borrowed from the Alpha 7 II and has the ability to shoot and record 4K videos in multiple formats including Super 35mm (without pixel binning) and full-frame format. Sony claims the AF response in Alpha 7R II is up to 40 per cent faster than the original Alpha 7R, thanks to 399 focal plane phase detection AF points.
Sony says the sensor inside the Alpha 7R II combines gapless on-chip lens design and AR (anti-reflective) coating on the surface of the sensor’s glass seal to “dramatically improve light collection efficiency, resulting in high-sensitivity with low-noise performance and wide dynamic range (ISO 100-25600, expandable to 50-1024002).” The new Alpha 7R II features the BIONZ X image processing engine with no optical low pass filter on the camera.
