Sony Announces Alpha 7R IV Camera with World’s First 35mm Full-frame 61.0 MP back-illuminated Exmor R CMOS image sensor
Sony today announced the latest addition to its acclaimed Alpha 7R series full-frame mirrorless camera line-up; the extremely versatile, powerful Alpha 7R IV (model ILCE-7RM4). Sony Alpha 7R IV is World’s first 35mm full-frame 61.0 MP back-illuminated Exmor R CMOS image sensor with latest-generation BIONZ X image processor. To maximise durability, the new Sony Alpha 7R IV features upgraded dust and moisture resistance,[xix] with additional sealing provided at all body seams, the battery compartment cover and media slots. The camera is built with an extremely lightweight and durable magnesium alloy, and has an upgraded six screw, extra-firm mount.
The new Alpha 7R IV delivers stunning image quality with high resolution and wide dynamic range while maintaining outstanding focusing performance, high-speed continuous shooting and much, much more. The new Alpha 7R IV features a newly developed 35mm full-frame back illuminated CMOS image sensor with a resolution of 61.0 MP,ii the world’s firsti of its kind. The new sensor’s back-illuminated structure and effective noise reduction techniques combine to deliver extremely low-noise, high sensitivity performance ensuring the absolute maximum image quality. The camera also boasts an impressive 15-stop dynamic range at low sensitivities, resulting in smooth natural gradations ranging from deep shadows to highlights.
The full-frame powerful Alpha 7R IV camera is equipped with an innovative 5-axis optical in-body image stabilisation system that has been fine-tuned to support its high-resolution shooting capacity, resulting in a shutter speed advantage of 5.5-steps. The shutter unit assembly has been carefully re-designed to reduce even the slightest movement that may cause blur.
The Alpha 7R IV also includes Sony’s highest resolution viewfinder in any camera, a 5.76 million dot UXGA OLED Tru-finder EVF. About 1.6x the resolution of the EVF in the Alpha 7R III, this new viewfinder provides an extremely accurate, true-to-life depiction of the scene being framed. The display quality can be set to ‘Standard’ or ‘High’ mode, and to either 60 fps or 120 fps refresh rate to best match the subject and shooting conditions.
The new Sony camera features an evolved Pixel Shift Multi Shooting mode that composites up to 16 full-resolution images. In this mode, the camera precisely shifts the sensor in 1 or 0.5-pixel increments to capture 16 separate pixel-shifted images containing a total of 963.2 million pixels worth of data then composited into a 240.8 million pixels (19008 x 12672 pixels) image using the Imaging Edge desktop application. This enhanced mode produces photographs with a level of detail and colour accuracy that is simply stunning.
The upgraded focusing system of the Alpha 7R IV is comprised of 567 focal-plane phase-detection AF points that cover approximately 74% of the image area. There are also 425 contrast AF points that add extra precision and reliability for low light and other situations that are best served by contrast AF. The higher AF sensor density and refined tracking algorithms of the new camera produce a notable improvement in tracking performance, allowing complex subject motion and sudden subject movements to be reliably tracked with greater precision than ever. The Alpha 7R IV also supports Real-time Eye AF, which employs artificial intelligence to detect and process eye location data in real-time, stay locked onto the subject’s eye with extreme precision. This is available for both animal and human subjects, with an option to select either animal or human Eye AF mode depending on the shooting situation.
Sony’s new Alpha 7R IV full-frame camera includes wireless LAN functionality to support the conventional 2.4 GHz band as well as a high-speed 5 GHz band for faster, more stable data transfer. Wireless PC remote connectivity (wireless tethering shooting) is also available on the new Alpha 7R IV.
In addition to high-speed Wi-Fi and wireless PC connectivity, the new full-frame camera is equipped with a SuperSpeed USB (USB 3.2 Gen 1) USB Type-C connector .It also supports FTP data transfer with background transfer capability, allowing photographers to send images to a specified FTP remote server while they are still shooting or reviewing images. The new Alpha 7R IV Full-frame Interchangeable Lens Camera will ship in Europe in August 2019, priced at approximately £3,500 and €4,000.
