Optimized video, optimized sensitivity, optimized speed, the Sony Alpha a7S III raises the bar for what a full-frame mirrorless camera is capable of. A revised 12.1MP Exmor R BSI CMOS sensor and updated BIONZ XR image processor offer faster performance, improved noise reduction, and a wider dynamic range, along with UHD 4K 120p video recording and internal 10-bit 4:2:2 sampling.

Video is the primary application of the a7S III, and improvements to the sensor and processor enable faster readout speeds and greatly reduced rolling shutter, along with high-bitrate internal recording, 16-bit raw output via the full-size HDMI port, and flexible control over motion with variable frame rate selection. The a7S III also does away with recording time limits and incorporates HLG for direct HDR production as well as S-Log2/S-Log3 gamma profiles for advanced HDR production with editing.

The updated sensor design also brings improved autofocus performance via 759 phase-detection points, which offer intelligent subject tracking and Real-time Eye AF to ensure critical focus on moving subjects in all recording modes. The sensor and BIONZ XR processor also facilitate impressive sensitivity, with an expanded range from ISO 40-409600, as well as fast 10 fps continuous shooting for up to 1000 consecutive raw frames. Additionally, 5-axis SteadyShot INSIDE sensor-shift image stabilization is available, too, which minimizes the appearance of camera shake by up to 5.5 stops.

Complementing the imaging assets, Sony has also made some changes to the a7S III's physical design, including a rear LCD with a side-open articulating design and an impressive 9.44m-dot OLED electronic viewfinder. The camera's menu system has also been updated for more intuitive navigation and the body design helps to promote better heat dissipation for improved continuous recording capabilities. Additionally, dual memory card slots both support working with CFexpress Type A or SD UHS-II memory cards for flexible and high-speed file storage.

12.1MP Exmor RS BSI CMOS Sensor and BIONZ XR Image Processor

A redesigned 12.1MP full-frame CMOS sensor now features a back-illuminated Exmor RS design in order to achieve improved clarity and reduced noise along with the expectedly impressive sensitivity, from ISO 80-102400 with an extended ISO 40-409600 range. The updated sensor design also yields 2x faster readout speeds than previous generations and, when coupled with the revised BIONZ XR image processor, greatly reduces rolling shutter by 3x and up to 8x faster processing and overall camera handling. The sensor and processor combination also helps to achieve a wide dynamic range, of up to approximately 14 stops for stills and 15 stops for video, and 10 fps continuous shooting for up to 1000 uncompressed raw files for stills.

UHD 4K 120p Video, 10-Bit 4:2:2 Internal Recording

Recording up to UHD 4K is possible with frame rates up to 120p, using full 1:1 pixel readout without binning. Internal 10-bit 4:2:2 sampling is also possible in all recording modes and, if recording externally via the full-size HDMI A port, 16-bit raw output is also possible for even greater tonal reproduction and post-production flexibility. Additionally, two codecs have also been developed: XAVC HS, which uses HEVC/H.265 encoding to retain more detail at smaller bitrates, and XAVC S-I, which is an intraframe codec for consistent performance and quality at bitrates up to 600 Mb/s.

The high-speed, 120 fps recording also enables 4x and 5x slow-motion movie recording with the frame rate playback set to either 30p or 24p or, if moving down to Full HD resolution, an effective 240p frame rate is also available for even greater motion control. Additionally, suiting long-form recording, the a7S III does not have any recording time limits to allow for unlimited clip lengths. The camera's physical design also features an improved heat-dissipating structure to promote longer possible recording times, up to an approximate 60-minute recording time at 4K60p.

Affording extensive customizable color and gamma controls, the a7S III allows users to adjust the gamma, black level, knee, color level, and more. Also, users can use the same S-Log2 Gamma Curve that is found on high end Sony Cinema cameras that squeezes up to 1300% more dynamic range into the video signal then traditional REC709, for increased post-production flexibility. HLG (Hybrid Log-Gamma) support is also available, along with the BT.2020 color space, for recording within a wide color gamut and, in addition to S-Log2, S-Log3 is also available for producing a 15+-stop dynamic range with increased grading control in the shadow to mid-tone regions of the image.

Fast Hybrid AF System

Covering 92% of the image area, a Fast Hybrid AF system incorporates 759 phase-detection points along with 425 contrast-detection areas for quick and precise focusing in a variety of lighting conditions with sensitivity down to -6 EV. This focusing system is available for use in all recording modes, to benefit both video and stills applications. Additionally, it is able to lock onto subjects quickly and can use Real-time Tracking for AI-based tracking on moving subjects or touch tracking for manual selection of the subject. Real-time Eye AF, suitable for both humans and animals, also ensures critical sharpness when shooting portraits. Helping to fine-tune how the focusing system performs, seven-step AF transition speed and five-step AF subject shift sensitivity controls let you refine how quickly focus shifts from point to point and how smoothly focusing shifts occur.

5-Axis SteadyShot INSIDE Image Stabilization

The a7S III incorporates an enhanced 5.5-stop effective 5-axis SteadyShot INSIDE image stabilization system, which compensates for five different types of camera shake encountered during handheld shooting of stills and video. This allows users to confidently use any lens, even adapted lenses, for critical imaging without encountering blur from camera shake.

For long focal lengths, the system will correct for pitch and yaw adjustments. Macro and high-magnification imagery, on the other hand, will benefit from the inclusion of horizontal and vertical shift compensation. All shooting styles will get usage out of the roll compensation. All 5 axes of stabilization will function at all times, even when used with third-party lenses and adapters or lenses with built-in optical stabilization.

Additionally, specifically for video, there is also an Active IS mode that adds even more precise stabilization methods for even smoother footage straight out of camera.

New image sensor with double the readout speed

The newly developed back-illuminated full-frame Exmor R^TM CMOS sensor, with 12.1 effective megapixels², boasts a readout speed up to twice as fast as that of the α7S 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 XR^TM 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 stops⁴, 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<sup>1</sup>

Full-frame 4K recording at 120p¹

Full-frame 4K recording at 120 fps¹ 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 α7S 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 α7S III supports internal intra-frame (All-Intra) recording⁶ for the first time in an α-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. [1] All-Intra (All-I) [2] Long GoP [3] Group of Pictures.

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 even better image quality as well as manageable file sizes⁷.

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 α 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)⁸.

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 stops⁴. 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 α7S 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)⁹.

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. [1] High flexibility to fine-tune images as desired (color grading required) [2] Instant high-quality image (color grading not required).

Enhanced movie image quality

Thanks to the improved capabilities of the α7S 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 α7S 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<sup>1</sup>

Active Mode optical image stabilization for handheld shooting¹

Relying on a new high-precision stabilization unit, gyro sensors, and optimized image stabilization algorithms, the camera's Optical SteadyShot^TM Active Mode provides the precise degree of optical image compensation needed during movie shooting, even for 4K video¹⁰. 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 α system. [1] Track of camera shake [2] Standard [3] Active.

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 Adaptor 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 Adaptor 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 Σ (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-dot² LCD screen. The MOVIE button is within easy reach on the camera's top panel, and a durable HDMI Type-A terminal ensures reliable connections to external monitors. The item arrangement and initial settings on the mode dial have also been adjusted to meet the needs of pro users.

Dedicated settings menu for movie shooting

A subset of the camera's settings can be changed independently for movie or still shooting, which can be useful if you want to use different ISO, Iris (aperture) and other settings depending on the shooting mode. Another convenient feature is the use of Flexible Exposure Mode instead of normal PASM Mode when Movie or S&Q mode is selected. This allows quick switching between auto and manual control of Iris (aperture) and shutter speed, and the function can be assigned to a custom button to allow one-touch toggling between auto and manual.

New image sensor with double the readout speed
