About Sony Alpha a7S III
FEATURED REVIEWS
Absolutely unique at this price, and without real competition for most video use up our $72K ARRI.
We use a range of video and stills cameras, from Canon, Panasonic, SONY, ARRI and Phase One. This is the first camera that I have used that enables an entirely new level of low-light creative video and stills options-- far beyond our new Canon R5, the ARRI or anything else we have.
Wonderful wonder!
Just great, excelent sensor! I use a7SIII for video and Nikon Z system for photos and after trying Canon RF mount too, this 2 systems are far superior thanks to quality on E mount glass and Z glass. You earn avoiding Chromatic Aberrations of expensive RF glasses and softness.
a7S III with pro movie/still capability
Designed for professionals, the a7S III builds on the strengths of the S series, such as high sensitivity and wide dynamic range, while providing pro features like enhanced AF, optical image stabilization and 4K 120p recording. Incorporating a powerful new engine in its compact body, the camera delivers a wide range of visual experiences.
New image sensor with double the readout speed
The newly developed back-illuminated full-frame Exmor RTM CMOS sensor, with 12.1 effective megapixels, boasts a readout speed up to twice as fast as that of the a7S II, along with high sensitivity and wide dynamic range. An advanced color filter array boosts color reproduction accuracy, while focal plane phase-detection AF enables substantial increases in autofocus stability and precision, all of which contribute to outstanding image quality.
New image-processing engine with up to 8x the processing performance
The BIONZ XRTM image-processing engine boasts a performance level up to eight times that of the previous processor, minimizing latency while markedly improving real-time processing capabilities for both movies and stills. The engine performs real-time processing of AF, image recognition and image-quality adjustments, while also handling data transfer, user interface and other camera operations.
High sensitivity, wide dynamic range
The full-frame 12.1-megapixel3 configuration enables high sensitivity with low noise throughout the camera's sensitivity range by optimizing the output signal from the sensor. The standard ISO range is 80-102400, which is further expandable to 40-409600 (80-409600 for movies). The dynamic range is an impressively wide 15 stops, for beautiful, true-to-life images without blown highlights. Together, the camera's high sensitivity and wide dynamic range expand your creative freedom during shoots.
Full-frame 4K recording at 120p
Full-frame 4K recording at 120 fps with autofocus is possible thanks to the high-speed readout capabilities of the new image sensor working in tandem with the newly developed, powerful BIONZ XR processor. This high image-quality 4K, with full-pixel readout without binning, allows for clear post-produced slow motion (up to 5x slower than real time)5, as well as bokeh effects typical of full-frame cameras, all with smooth, high-precision autofocus. Despite the a7S III's compact size, it provides impressive scope for your creativity.
Recording movies with 10-bit depth and 4:2:2 color sampling
The camera is capable of performing 4K internal recording with 10-bit depth and 4:2:2 color sampling when using either Long GOP or All Intra compression. This makes it possible to push your color grades further, stretching video out for ultimate HDR realism while still retaining natural gradation, for true editing freedom.
All-Intra internal recording
In addition to Long GOP inter-frame compression, the a7S III supports internal intra-frame (All-Intra) recording6 for the first time in an a-model body, where each frame is recorded independently at a high bitrate of up to 600 Mbps. This can be useful for certain types of shoots as it allows maximum flexibility in post-production editing.

HEVC codec with high compression efficiency
Available for the first time, XAVC HS-format recording using the MPEG-H HEVC/H.265 codec roughly doubles the compression efficiency. Compared to a normal 4K XAVC S format, XAVC HS allows for detailed 10-bit video with 4:2:2 color sampling at comparable or lower data rates, delivering
16-bit RAW data output
Facilitating improved image quality and more flexible and efficient editing in post-production, the camera supports 16-bit RAW data output to an external recorder via HDMI, for the first time in the a series. The output is full-frame 4264 x 2408 (16:9 aspect ratio) 16-bit data from the image sensor, with a choice of frame rates (60p/50p/30p/25p/24p)
S-Log2 and S-Log3 with 10 bit 4:2:2 support
S-Log2 and S-Log3 gamma curves are available, with S-Log3 designed for better reproduction of gradations from shadows to the mid-gray range (18% gray), enabling a dynamic range of up to 15 stops. Three color gamut settings (S-Gamut, S-Gamut3, and S-Gamut3.Cine) are provided, and the latter two settings make it easier to match the colors of footage shot with Sony's professional cinema cameras. Because the colors match, color grading is easier in post-production editing, making it more convenient to use the a7S III along with other pro cameras.
Proxy recording for more efficient editing workflow
When shooting movies, low bit-rate HD proxy files can be recorded simultaneously with higher bit-rate formats such as XAVC S-I 4K, and these smaller proxy files can then be used for editing and previewing prior to final production delivery. This reduces computer load and allows faster and more efficient workflows. Proxy files can be captured in either 10-bit XAVC HS (1920 x 1080) or 8-bit XAVC S (1280 x 720)
10-bit HLG picture profile
An HLG (Hybrid Log-Gamma) HDR picture profile, complete with the wide-gamut BT.2020 color space, can be used for direct HDR (HLG) playback on compatible TVs. The result is true-to-life imagery close to what the naked eye can see, with detailed shadows and highlights, less blackout and less whiteout, all without the need for color grading. In particular, 10-bit recordings reproduce a level of fine gradation and detail for extraordinary realism.

Enhanced movie image quality
Thanks to the improved capabilities of the a7S III's new image-processing engine, colors and textures of foliage and human skin can be more consistently reproduced without over-dependence on light sources. Gradation rendering has also been refined, for better-looking skin tones and highlight roll-off in portraits. When shooting 4K, the new image sensor and processing engine reduce rolling shutter distortion to as little as one-third that of the a7S II.
Fast Hybrid AF for dependable focus during movie shooting
Inheriting technology and performance standards from Sony's large-format FX9 pro camcorder, Fast Hybrid AF combines focal plane phase-detection AF with contrast-detection AF. This results in highly precise, smooth tracking of fast-moving subjects even over a wide range with a shallow depth of field, taking full advantage of Sony E-mount lenses' smooth linear-motor focusing and power-zoom operations. Newly added AF Transition Speed and AF Subject Shift Sensitivity parameters allow more flexible focus control, as requested by professional users. Both allow preset settings to be recalled during recording by using a customizable button.
AF support in manual-focus mode
The camera's autofocus support can be useful even when you're primarily using manual focus. For full AF speed, half-press the shutter button or press the AF-ON button, as you would when shooting stills. Alternatively, slower, more cinematic AF transitions can be achieved by initiating AF via the touch focus feature or Real-time Eye AF via a custom button assignment, resulting in slow, smooth autofocus at the preset AF Transition Speed.
Game-changing tracking features to revolutionize movie shooting
Real-time Tracking and Real-time Eye AF make movie-making much easier. Touch Tracking initiates subject tracking with an intuitive touch to the LCD monitor, processing data on color, pattern (brightness), distance (depth) and facial information to keep your subject in steady focus. You can then concentrate more fully on composition, which can be especially useful when you're shooting solo or using a gimbal. Touch operations can be used to temporarily engage AF even when you're shooting manually.
Active Mode optical image stabilization for handheld shooting
Relying on a new high-precision stabilization unit, gyro sensors, and optimized image stabilization algorithms, the camera's Optical SteadyShotTM Active Mode provides the precise degree of optical image compensation needed during movie shooting, even for 4K video. With this unprecedented level of stabilization it's possible to shoot with the camera only, taking advantage of the compact size and mobility of the a system.

Enhanced audio quality
A digital audio interface is incorporated in the camera's Multi Interface (MI) Shoe, to facilitate cleaner, clearer audio recordings without loss of quality. The XLR-K3M XLR Adapter Kit additionally provides the camera with 4-channel 24-bit digital audio recording capability. Three recording formats can be selected from a menu: 48 kHz/16-bit 2-ch, 48 kHz/24-bit 2-ch, and 48 kHz/24-bit 4-ch, with the XLR-K3M XLR Adapter Kit required for the latter two formats.
New heat-dissipation design for extended recording times
The camera's design has been optimized to prevent overheating even during extended recording sessions. A unique Sony sigma shaped graphite-alloy heatsink is built into the image stabilization unit, allowing the sensor to dissipate heat five times more effectively than in previous models11, while allowing it to move freely and avoiding interference with the stabilization system.
Designed for smooth movie-making
Flexibility in positioning the camera and framing shots is provided by the side-opening, vari-angle monitor, which incorporates a bright 3.0-type, 1.44 million-dot LCD screen.
