Alongside releasing impressive Xperia-branded smartphones, Sony takes yet another step in redefining the imaging industry with the launch of its new flagship full-frame mirrorless camera, the α7R II.

This interchangeable lens camera features the world's first back-illuminated full-frame Exmor R CMOS sensor, which realises high-resolution (approximately 42.4 effective megapixels), high-sensitivity (expandable up to ISO 102400) and high-speed AF response up to 40% faster than the original α7R, thanks to 399 focal plane phase detection AF points.

The camera also includes a 5-axis image stabilisation system borrowed from the acclaimed α7 II model, and has the ability to shoot and record 4K videos in multiple formats including Super 35mm (without pixel binning) and full-frame format, a world's first for digital cameras. Additionally, it has a newly refined XGA OLED Tru-Finder with the world's highest (0.78x) viewfinder magnification.

Sony has said the 42.4-megapixel sensor 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. This allows the camera to shoot at an impressive ISO range of 100 to 25600 that is expandable to ISO 50 to 1024002.

An ideal match to Sony's extensive collection of FE lenses (35mm full-frame compatible E-mount lenses), the new α7R II features a high-speed BIONZ X image processing engine that allows images and videos from the camera to be captured with supreme details and low noise. There is also no optical low pass filter on the camera, ensuring that scenery and landscapes are captured in the highest possible resolution and clarity.

The new α7R II camera is Wi-Fi and NFC-compatible, and is fully functional with Sony's PlayMemories Mobile application available for Android and iOS platforms, as well as Sony's growing range of PlayMemories Camera Apps, which add a range of creative capabilities to the camera.

Along with α7R II, Sony has also launched two more CyberShot cameras in its CyberShot RX portfolio. Named as RX100 IV and RX10 IV, offers high frame rate snapping experience by offering 960 frames in a span of two seconds. They will also allow clicking slow-motion videos and the latest 4K video-recording capability.

The RX10 II packs a one-inch 20mp sensor based on Stacked Sensor Technology and offers much bigger images with more effective pixels.

The RX100 IV and RX10 IV will also offer rapid shutter speed of 1/32,000 second to help you freeze birds or sport stars in motion.

The actual difference between the models is the featured lens and aperture. The Cybershot RX10 II packs a 200mm lens with f/2.8 aperture lens, while RX10 IV features a 24-70mm lens with a varied aperture of f/1.8 to f/2.8.

The low aperture of both the cameras will help users to click better low-light and high-speed images. While the 200mm lens of RX10 II will offer better telephoto images like sports or wildlife photography, the 24-70mm lens of RX100 IV will offer wide angle, portrait and macro photography options.

Sony CyberShot RX100 IV and CyberShot RX10 IV has been made available for Rs 69,990 and Rs 94,990 respectively, while the α7R II is priced for Rs 2,39,990 and will be available across all Sony Alpha flagship stores and brand stores.
