Gain control of expressive freedom
With outstanding imaging capability and high-speed performance contained in a compact body, the a7 III gives you the power, precision, and flexibility to capture once-in-a-lifetime moments just as you like. A newly developed back-illuminated image sensor and evolved image processing system fulfil various shooting needs with high-quality imaging capabilities that you would expect only of a full-frame camera.
Newly developed sensor, evolved image processor
A new version of the 24.2-megapixel5 Exmor R™ CMOS sensor, now featuring a back-illuminated structure, is combined with the latest BIONZ X™ image processing engine and front-end LSI, and this combination achieves a data readout speed that is two times faster and data processing capability that is 1.8 times higher.
Back-illuminated full-frame sensor
The 35-mm full-frame CMOS image sensor with back-illuminated structure enhances light collection efficiency, expands circuitry scale, and, with the help of a copper wiring layer that contributes to quicker data transfer, outputs data at very high speed while minimising noise to reveal fine details in every picture.
Reducing noise in high-resolution images
Standard ISO range is extended to ISO 100-51200 (expandable to ISO 50-2048007 for stills), while Detail Reproduction and Area-specific Noise Reduction technologies maintain image details and cut noise. With highly effective performance in mid-to-high sensitivity ranges, you can shoot at high ISO with no concerns about noise or image deterioration.
Subtle gradation from shadow to highlight
Approximately 15-stop dynamic range at low-sensitivity settings is achieved, thanks to a revamped CMOS sensor and image processor that provide for smooth gradation from shadow to highlight. This gives you greater freedom of creative imaging.
Faithful colour reproduction
Colour reproduction performance is dramatically enhanced, giving subjects that you capture more natural colour that is faithful to how the colours look in real life. Skin tones in portraits, blue skies in landscapes, and vivid hues in still life images look very realistic as a result.
Steadier shots with 5-axis stabilisation
The latest high-precision stabilisation uses stabilisation unit and gyro sensors and algorithms to achieve a 5.0-step shutter speed advantage in a system that compensates five types of camera shake with a wide range of lenses and delivers excellent performance.
14-bit RAW output for rich gradations
For smoother, more natural gradation, the latest BIONZ X image processor and front-end LSI process image signals in 16-bit form. This processor also allows 14-bit RAW data output, even when in silent or continuous photographing mode.
4D FOCUS - AF performance evolves
AF performance is improved using the same AF advancements as in the a9 and applying it optimally. Once the a7 III captures such unpredictably moving subjects as dancers, boxers, and wild animals in action, it won’t easily let them go. The Sony Apha a7 III features 693 phase-detection AF points covering approx. 93% of image area, plus 425 densely positioned contrast-detection AF points to improve focus.
Up to two times faster AF performance
Combining focal-plane phase-detection AF for excellent speed and tracking plus high-precision contrast-detection AF, Sony’s sophisticated Fast Hybrid AF can capture fast-moving subjects in razor-sharp images. This system advances performance to double AF speed.
Enhanced AF tracking for swiftly moving subjects
The AF performance inherited from the a9 accounts for AF tracking with enhanced precision for continuous shooting of quick action. With faster image sensor readout, even complex subject motion can be tracked and sudden movements can be predicted with great precision, letting you capture decisive moments.
Eye AF revolutionises portraiture
With the a7 III, Eye AF can now be used with AF-C mode, for fast, effective eye detection/tracking performance when shooting stills. The easy maintenance of optimum focus on moving subjects can totally transform your portraiture.
Fast continuous shooting captures the height of a moment
The a7 III can shoot in a continuous burst at up to 10 fps with AF/AE tracking and up to 8 fps burst shooting when shooting with live-view mode. The camera also supports silent shooting at up to 10 fps with AF/AE tracking at maximum resolution.
High-resolution 4K HDR
As well as new capability of recording stunning 4K movies through 2.4x higher oversampling, the camera features a new HLG (Hybrid Log-Gamma) picture profile, supporting instant HDR workflow. Full-pixel readout without binning in 35-mm full-frame mode makes it possible to condense approx. 2.4 times the data required for 4K movies (QFHD: 3840 x 2160), minimising moiré and jaggies. Full-frame or Super 35-mm mode can be selected as needed. Furthermore, 4K recording employs XAVC S format at bitrates as high as 100 Mbps.
Improved Fast Hybrid AF for movie recording
Fast Hybrid AF with focal-plane phase-detection AF and contrast-detection AF locks onto and smoothly tracks moving subjects. A wide AF area like that for still images is now available for movies, too. Reduced low-end AF drive speed allows more pronounced slow focus effects. Freedom to match focus response to specific scenes is enhanced overall.
HLG (Hybrid Log-Gamma) for instant HDR workflow
A new HLG picture profile supports instantaneous HDR workflow. Movies recorded in HLG picture mode will appear true-to-life with minimized black-crush or blown highlights that can deteriorate gradation and details, without colour grading.
Supports S-Log3 and Slow and Quick Motion
S-Log3 improves gradation from shadows to mid-tones and widens the dynamic range up to 14 stops. Also, select a frame rate from 1 to 120/100 fps for up to 60x quick motion and 5x slow motion.
