Distinguished by its updated sensor design, the Alpha a7 III Mirrorless Digital Camera from Sony is a well-rounded camera suitable for both photo and video applications in a variety of working situations. Refined for improved speed and low-light performance, the full-frame 24.2MP Exmor R BSI CMOS sensor and BIONZ X image processor pair to realize an impressive 10 fps continuous shooting rate and improved autofocus performance for faster, more reliable subject tracking along with wide frame coverage.
This updated Fast Hybrid AF System employs a combination of 693 phase-detection points and 425 contrast-detection areas for quicker acquirement of focus in a variety of lighting conditions, and also maintains focus on subjects more effectively. In addition to speed and AF, the processing improvements also help to realize greater image clarity and reduced noise throughout the sensitivity range from ISO 100-51200, which can further be expanded to ISO 50-204800.
Video recording capabilities have also been extended for enhanced quality when recording UHD 4K video with the full width of the full-frame sensor to minimize moiré and aliasing. Additionally, benefitting both stills and video operation, the a7 III utilizes a 5-axis SteadyShot INSIDE sensor-shift image stabilization, which is now effective to minimize the appearance of camera shake by up to 5 stops.
Perfection for all. Everything you need.
Capture the peaks of more decisive moments with the α7 III from Sony, packing newly developed back-illuminated full-frame CMOS sensor and other advanced imaging innovations, high-speed response, ease of operation, and reliable durability that are ready for various shooting needs.
Animal-eye AF feature now available with software update
A software upgrade is now available to support Sony’s new Real-time Eye AF for Animals. The feature works by automatically detecting and tracking the eyes of animals that you’re photographing, for beautiful pet portraits and wildlife shots.
Gain control of expressive freedom
With outstanding imaging capability and high-speed performance contained in a compact body, the α7 III gives you the power, precision, and flexibility to capture once-in-a-lifetime moments just as you like.
Rendering scenes in realistic detail
A newly developed back-illuminated image sensor and evolved image processing system fulfill various shooting needs with high-quality imaging capabilities that you would expect only of a full-frame camera.
Newly developed sensor, evolved image processor
The latest technology achieves stunning processing speed
A new version of the 24.2-megapixel 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.
Reducing noise in high-resolution images
Up to 1.5-stop improvement6 in image quality
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.
Steadier shots with 5-axis stabilization
The latest high-precision stabilization uses stabilization unit and gyro sensors and algorithms to achieve a 5.0-step9 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 RAW10 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 RAW10 data output, even when in silent or continuous shooting mode.
4D FOCUS—AF performance evolves
AF performance is improved using the same AF advancements as in the α9 and applying it optimally. Once the α7 III captures such unpredictably moving subjects as dancers, boxers, and wild animals in action, it won’t easily let them go.
Reliable AF down to EV-3 brightness
Advanced AF algorithms contribute to high AF precision down to light levels as low as EV-3, for more reliable autofocus in dark scenes.
Focal-plane phase-detection AF supports A-mount lenses
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 revolutionizes 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.
Focus control via touch screen
The α7 III has Touch Focus function, and a Touch Pad function for you to fingertip-drag the focus frame intuitively while using the viewfinder.
AF in Focus Magnifier
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.
More versatile AF settings all around
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 10fps with AF/AE tracking and up to 8fps burst shooting when shooting with live-view mode. The camera also supports silent shooting at up to 10fps with AF/AE tracking at maximum resolution.
Confidence-boosting continuous shooting
Capture an instant action with continuous shooting of up to 10fps—or 8fps for live-view shooting—with AF/AE tracking2. Up to approximately 177 JPEG (standard) images, 89 compressed RAW images, or 40 uncompressed RAW images can be captured in one continuous burst.
Shoot continuously in absolute silence
This camera allows silent shooting at up to 10fps with AF/AE tracking2. Silence is critical for various scenes, when even slight noise can mean missing a chance at an ideal shot.
When artificial lighting flicker is detected, the shutter is timed to minimize possible exposure and colour inconsistency in images shot at high shutter speeds, as well as between continuous shots.
Better operation during continuous shooting
Groups of shots taken in continuous mode can be reviewed, deleted, or protected quickly. You can access a menu screen and change settings21, as well as operate image playback during data writing.
High-resolution 4K HDR
As well as new capability of recording stunning 4K movies through 2.4-times higher oversampling, the camera features a new HLG (Hybrid Log-Gamma)4 picture profile, supporting instant HDR workflow.
Image resolution uncompromised
Full-pixel readout without binning for high-resolution 4K movies
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), minimizing moiré and jaggies. Full-frame or Super 35-mm mode can be selected as needed. Furthermore, 4K recording3 employs XAVC S format at bitrates as high as 100 Mbps.
HLG (Hybrid Log-Gamma)4 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 color grading.
Supports S-Log and Slow and Quick Motion
S-Log 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 fps24 for up to 60x quick motion and 5x slow motion.
