Sony announced a follow-up to its 2017 A7R III full-frame mirrorless camera. Simply called the, the A7R IV, the new camera boasts of some big upgrades over the previous model, which was already feature-packed to begin with. The ‘R' moniker in the A7 series stands for resolution and the new model boasts of a brand new 61-megapixel sensor, which is big step-up from the 42.4-megapixel sensor in the previous model. Apart from that, the camera also boasts of having 15-stop dynamic range, fast burst shooting, a new real-time Eye AF for video, upgraded electronic viewfinder (EVF), and professional 4K shooting modes. The new camera will begin shipping in September for $3,500 (roughly Rs. 2,40,700).
The highlight of the A7R IV is of course that 61-megapixel BSI CMOS sensor, which Sony claims is the first of its kind. Sony's Pixel Shift Multi Shooting is also present, which shoots 16 high-resolution images, with a slight shift in sensor positioning for each image, either by one or half a pixel. You can then composite all the images in Sony's Imaging Edge software, for an effective 240.8-megapixel resolution image.
Some of the basic specifications include an ISO range of 100-32,000 (expandable), 567 PDAF and 425 contrast detection autofocus points, E-mount, and Sony's BIONZ X image processor. The new camera might look similar to the older model but Sony says it has made some upgrades to the design and usability. The aluminium alloy body gets additional sealing at all the seams for dust and moisture resistance. There's a wider hand grip, new multi-selector joystick, and redesigned shape and position of the rear dial. Both card slots are also UHS-II compliant.
