The Alpha a7R III Mirrorless Digital Camera from Sony is a versatile, high-performance camera characterized by not only its resolution but by its multimedia versatility. the a7R III affords an impressive 10 fps continuous shooting rate along with improved autofocus performance for faster, more reliable subject tracking along with wide frame coverage. In addition to speed and AF, the processing improvements also help to realize greater image clarity throughout the sensitivity range from ISO 100-32000, which can further be expanded to ISO 50-102400. Video recording capabilities have also been extended for enhanced quality when recording UHD 4K video with the full width of the full-frame sensor, or when using a Super35 area and 5K oversampling to minimize moiré and aliasing. the a7R III also sports a revised body design, which includes a 3.69m-dot Tru-Finder OLED electronic viewfinder for bright, clear, and realistic eye-level monitoring. A rear 3.0" 1.44m-dot tilting touchscreen LCD is also available for intuitive settings control and to better support working from high and low angles. 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. Also, the copper wiring layer dramatically improves data transmission speed for creating 14-bit, high-resolution 42.4-megapixel stills with a native sensitivity range from ISO 100-32000, which can be further expanded to ISO 50-102400. This Fast Hybrid AF System now achieves twice the focusing speed and more reliable tracking compared to previous a7R models, as well as improved low-light focusing response down to -3 EV. Additionally, Eye AF can be used to base focus on recognized subjects' eyes for portraits and is available in both AF-S and AF-C modes. Autofocus can also be used in conjunction with the Focus Magnifier function for critical focus when homing in on minute subject details Full-frame 4K recording has also been dramatically improved for improved quality when working at mid to high sensitivities to permit full use of the entire sensor width. Full HD 1080p recording is also supported in frame rates up to 120 fps, and both resolutions utilize the 100 Mbps XAVC S format contained within an MP4 wrapper with 4:2:0 sampling. UHD 4K movies and lower-resolution proxy movies can be simultaneously recorded. The smaller proxy files are ideal for quick previewing or pre-editing that can reduce the time required for final 4K editing. Magnesium alloy chassis assures rigidity, durability, and stability while remaining lightweight. The lens mount has also been improved to better support heavy lenses and the grip rigidity has been improved for more comfortable hand-holding. The a7R III features a 3.5mm microphone input jack for compatibility with external microphones. And for users needing more, the camera is also compatible with the Sony XLR-K2M XLR Adapter for recording professional balanced XLR audio signals with phantom power and adjustable mic/line inputs.
