Rendering scenes in realistic detail
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. A new version of the 24.2-megapixel4 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 data readout speed that is two times faster and data processing capability that is 1.8 times higher.
The camera’s 35mm 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.
Standard ISO range is extended to ISO 100-51200 (expandable to ISO 50-2048006 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 and image deterioration.
Approx. 15-stop dynamic range7 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.
Colour reproduction performance is dramatically enhanced, giving subjects that you capture a 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.
The latest high-precision stabilisation uses a stabilisation unit, gyro sensors, and algorithms to achieve a 5.0-step shutter speed advantage in a system that compensates for five types of camera shake with a wide range of lenses and delivers excellent performance.
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 shooting mode.
Take aim with high AF performance
AF performance is improved using the same AF advancements as in the α9 and applying it optimally, so once the α7 III captures such unpredictably moving subjects as dancers, boxers, and wild animals in action, it won’t easily let them go.
This camera features 693 phase-detection AF points covering approx. 93% of image area plus 425 densely positioned contrast-detection AF points to improve focus and give stunning wide coverage.
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.
The AF performance inherited from the α9 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, allowing you to capture decisive moments.
Advanced AF algorithms contribute to high AF precision down to light levels as low as EV-314, for more reliable autofocus in dark scenes.
693-point focal-plane phase-detection AF not only covers a wide area and responds instantly — it offers the benefits of high tracking performance even with an A-mount lens mounted via mount adaptor LA-EA3.
Eye AF revolutionises portraiture
With the α7 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. This feature can be used even if the subject's face is partially hidden, looking down, or backlit, giving increased creative freedom.
The α7 III has a Touch Focus function, and a Touch Pad function for you to fingertip-drag the focus frame intuitively while using the viewfinder. Use autofocus for stills while the focus area is magnified in the viewfinder/monitor, and magnify the view after autofocusing. This is ideal for focusing on a small area and other precision-focus photography.
AF tracking sensitivity for stills is adjustable in five steps. AF areas/points are changeable as you switch between horizontal and vertical orientation. Focus point settings can be assigned to custom buttons.
Fast continuous shooting captures the height of a moment
The α7 III can shoot in a continuous burst at up to 10 fps with AF/AE tracking1 and up to 8 fps burst shooting when shooting with live-view mode. The camera also supports silent shooting17 at up to 10 fps with AF/AE tracking at maximum resolution.
Capture an instant action with continuous shooting of up to 10 fps — or 8 fps for live-view shooting — with AF/AE tracking. Up to approximately 177 JPEG (standard) images, 89 compressed RAW images, or 40 uncompressed RAW images can be captured in one continuous burst.
This camera allows silent shooting at up to 10 fps with AF/AE tracking. Silence is critical for various scenes when even slight noise can mean missing a chance at an ideal shot.
Artificial lighting flicker is detected and the shutter is timed to minimise possible exposure and colour inconsistency in images shot at high shutter speeds, as well as between continuous shots.
Groups of shots taken in continuous mode can be reviewed, deleted or protected quickly. You can access a menu screen and change settings, as well as operate image playback during data writing.
More realistic, expressive movies
As well as the new capability of recording stunning 4K movies through 2.4-times higher oversampling, the camera features a new HLG (Hybrid Log-Gamma) picture profile, supporting instant HDR workflow.
The image resolution is uncompromised by a full-pixel readout without binning for high-resolution 4K movies, and a full-pixel readout without binning in 35mm full-frame mode. This 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 35mm mode can be selected as needed. Furthermore, 4K recording employs XAVC S format at bitrates as high as 100 Mbps.
Fast Hybrid AF with focal-plane phase-detection AF and contrast-detection AF locks onto and smoothly tracks moving subjects. A wide AF area similar to 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.
A new HLG picture profile supports instantaneous HDR workflow. Movies recorded in HLG picture mode will appear true-to-life with minimised black-crush or blown highlights that can deteriorate gradation and details, without colour grading. This allows high flexibility to fine-tune images as desired, as well as an instant high-quality image (colour grading not required).
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.
Reliable features and operation in a compact body
The α7 III’s operability is enhanced by fast control during shooting, dazzlingly clear views through the Tru-Finder, versatile connectivity, extended shooting endurance from various power sources, plus high durability and resistance to wet and dusty conditions.
The α7 III can use an NP-FZ100 battery with approx. 2.2 times as much capacity as an NP-FW50 battery, allowing you to shoot up to approximately 710 photos24 with one full charge. BC-QZ1 optional battery charger allows quicker charging than charging via USB.
With two media slots, including one that’s UHS-II-compatible for fast data writing, the α7 III can simultaneously or relay record, separate RAW/JPEG data and stills/movies, and copy data between cards.
Register up to 30 frequently used items on the new My Menu for instant recall. You can create and customise an optimal menu for your own convenience.
With the rating function, you can rate recorded still images from 1 to 5 stars anywhere right on the spot, using the playback screen to perform the function if it is assigned to a custom button.
USB 3.1 Gen 1 compatible USB Type-C™ port makes high-speed PC Remote data transfer smooth and effortless, for handling large image files that are produced using PC-tethered shooting.
