Eye AF can be used when photographing animal subjects, too, with any focusing mode when shooting stills. Additionally, Eye AF can be used to base focus on recognized human subjects' eyes for portraits and is available in both AF-S and AF-C modes, for both stills and video. The apt focus system also lends itself to a variety of focusing functions for refined accuracy, including Lock-on AF, which maintains focus on moving subjects throughout the use of a configurable frame that is set over the desired moving subject, and Expand Flexible Spot, which employs neighboring focus points to retain focus on moving subjects even if the originally selected point loses focus. The use of phase-detection points also enables the use of A-mount lenses via the optional LA-EA3 or LA-EA1 lens mount adapters with full continuous AF/AE tracking compatibility. This focusing system also achieves especially quick speed and reliable tracking, as well as enhanced low-light focusing response down to -3 EV. The sensor and processor combination also avails fast continuous shooting at up to 10 fps at full resolution, for up to 68 consecutive frames, with full-time AF/AE.Īn updated Fast Hybrid AF system now employs a combination of 567 phase-detection points, which cover approximately 99.7% of the height and 74% of the width of the frame, along with 425 contrast-detection areas for reliable and quick autofocus and subject tracking performance. The BIONZ X processor also works in conjunction with a high-speed front-end LSI to realize faster processing times along with the ability to capture this impressive 15-stop dynamic range with smooth tonal rendering. Also, it enables internal UHD 4K video recording with a wide 14-stop dynamic range using either the full width of the full-frame sensor or an APS-C-sized area. Also, the copper wiring layer dramatically improves data transmission speed for creating 14-bit, high-resolution 61MP stills with a native sensitivity range from ISO 100-32000, which can be further expanded to ISO 50-102400. This sensor structure works with gapless on-chip lens design and an anti-reflection coating, as well as eliminating the optical low-pass filter, to improve light collection and enhance detail. Additionally, built-in Bluetooth and both 2.4 and 5 GHz Wi-Fi bands afford wireless transferring and remote camera control from linked mobile devices.įeaturing a back-illuminated design, the full-frame 61MP Exmor R CMOS sensor works with the BIONZ X image processor to offer impressively high-resolution stills and video while minimizing noise, improving speed, and achieving a wide 15-stop dynamic range. Dual SD card slots are both UHS-II-rated for faster performance and the inclusion of a USB Type-C port permits tethering and quick in-camera battery charging. In terms of usability, the OLED electronic viewfinder has been boosted to an impressive 5.76m-dot resolution for clear viewing and the 3.0" rear tilting touchscreen LCD has a high 2.36m-dot resolution for crisp playback, live view shooting, and menu navigation. Additionally, benefitting both stills and video operation, the a7R IVA retains the 5-axis SteadyShot INSIDE sensor-shift image stabilization, which is effective to minimize the appearance of camera shake by up to 5.5 stops.īalancing the imaging merits, the a7R IVA also sees an updated physical design with more robust weather sealing to suit working in especially harsh weather conditions. Despite being such a high-resolution sensor, it is also distinguished by its flexible native sensitivity range from ISO 100-32000 for working in a variety of lighting conditions. The revised sensor design uses a Fast Hybrid AF System, with 567 phase-detection autofocus points, for notably fast and accurate focusing performance. Up to 10 fps shooting is possible along with the ability to record UHD 4K30 video, both with support for Real-time Eye AF and Tracking AF technologies. This fourth edition of the a7R sees the inclusion of an updated 61MP Exmor R BSI CMOS sensor and enhanced BIONZ X image processor, which afford impressive imaging results with marked smoothness, a 15-stop dynamic range, and, of course, speed. Moving to an even higher resolution realm, the Sony Alpha a7R IVA continues the noteworthy series of highly capable full-frame cameras, characterized by impressive stills and video performance and versatility.
