Large pixels deliver high sensitivity and low noise
The new full-frame 12.1-megapixel
back-illuminated Exmor RTM CMOS image sensor packs major innovations in
light gathering, wiring and output optimisation. These deliver blazing
doubled readout speeds, superb image quality throughout the whole
sensitivity range, 15-stop wide dynamic range, and reduced rolling
shutter, with the sensor also providing focal-plane phase-detection AF.
Up to 8x more powerful4 BIONZ XRTM image processor
Along with the new sensor and its
unprecedented speed, the BIONZ XR image processing engine has also been
newly developed and packs up to 8x more processing power4. With a
future-oriented architecture, it delivers high-quality images faster for
superlative still and video expression, as well as dramatically
improved camera interface responsiveness.
10-bit 4:2:2 recording
Record right on the camera with the amazing
richness of 10-bit depth and 4:2:2 colour sampling, for far greater
flexibility in image grading, post-processing and compositing.
All-Intra encoding available
As well as Long GOP, All-Intra encoding is
now provided. This encodes every frame independently at bitrates up to
600 Mbps, to capture complex motions more accurately for recording on
either internal or external media, and allow more efficient editing

Superior quality and smaller files with XAVC HS
The new XAVC HS recording format uses
HEVC/H.265 encoding to achieve twice the compression efficiency of
AVC/H.264 encoding, for superior image quality and smaller file sizes.
Our renowned sensitivity delivers expanded ISO 409600
The renowned sensitivity of the series
scales new heights, with an expanded ISO range for movies from 80 to a
remarkable 409600 (standard range 80–102400). With advanced
light-gathering and output optimisation, the 12.1-megapixel2 full-frame
sensor achieves low noise throughout the sensitivity range, and can
capture usable images in near total darkness.
S-Log3 gamma, S-Gamut3.Cine gamut as on pro camcorders
The S-Log3 gamma curve and S-Gamut3.Cine
colour gamut, shared with pro camcorders, provide wider dynamic range
and easier colour matching for smoother post-production workflows.
HLG (Hybrid Log-Gamma)
HLG (Hybrid Log Gamma) simplifies HDR
production, producing footage for HLG-compatible BRAVIA TVs on the
camera with no complex post-production, and smooth gradations from the
10-bit colour depth.
 High flexibility to fine-tune images as desired (colour grading required)
 Instant high-quality image (colour grading not required)
Image quality improvements
The new BIONZ XR image processing engine
delivers improvements in colour reproduction, stability against
different light sources, natural tonal gradation and roll-off, and
reduced rolling shutter.
16-bit RAW HDMI output
For demanding post-production workflows,
16-bit RAW output6 is available via HDMI connection to compatible
external recorders7 while XAVC HS 4K, XAVC S 4K, or XAVC S-I 4K, and
proxy files are simultaneously captured in-camera.
Efficient editing through proxy recording
While recording high-bitrate 4K movies, HD
proxies (in 8 or 10-bit depth) can be generated in-camera8. Editing the
smaller proxy files reduces computer load and speeds up workflow prior
to final 4K delivery.
Fast Hybrid AF for accuracy and tenacity
The wide-area AF uses intelligent tracking
and on-sensor phase-detection covering most of the frame. The result is
that every bit of supremely accurate and tenacious AF performance is
extracted in combination with high-quality E-mount lenses, even when
shooting moving subjects at shallow depths-of-field in 4K and at 120p
Powerful focus control for solo shooters
With AF Transition Speed selectable over 7
levels, and AF Subject Shift Sensitivity over 5 levels, you can better
convey your creative intentions when switching subjects or, for example,
rack focusing. A simple touch can temporarily activate AF even during
manual focus operation.
Real-time Eye AF for movies
Real-time Eye AF uses AI to ensure pinpoint
focusing precision for eyes, with performance now improved by 30%9 on
profile or partially obscured faces. Tenacious eye tracking lets you
concentrate on composition even with a shallow focus depth.
Real-time Tracking with intuitive touch operation
Real-time Tracking analyses subject colour,
pattern, depth, and face information to track the subject. Touch

In-body 5-axis image stabilisation
A highly accurate image stabilisation unit and gyro-sensor are provided, delivering 5-axis optical image stabilisation.
 Yaw  Roll  Pitch
Active Mode for hand-held shooting
The new Active Mode10 11 provides increased
stabilisation for movie shooting. To preserve image quality, the BIONZ
XR processor accurately measures camera shake and compensates optically.
This makes stable video possible even when shooting hand-held where
space restraints prevent gimbal use, while walking, and at 4K
Digital audio interface for clear sound recording
A digital audio interface added to the
Multi Interface (MI) Shoe allows direct 24-bit input. Available settings
are 48 kHz/16-bit 2-ch, and by using the optional XLR-K3M adaptor kit,
48 kHz/24-bit 2-ch and 48 kHz/24-bit 4-ch.
Unique heat dissipation, for dependable recording
A unique Sony Σ (sigma) shaped graphite
heatsink is built into the image-stabilisation unit. This dissipates
heat 5x more effectively12 for extended recording time, without
interfering with image stabilisation.
Responding to feedback from professional
users, the MOVIE button has been moved to the top face for improved
operability in any shooting position. Mode dial ordering and speed of
switching have also been improved.
High ISO sensitivity
With an amazingly wide standard ISO range
of 80–102400 (expandable to 40–409600 for stills), the α7S III offers
incredible creative opportunities. The newly developed image sensor and
image processing algorithms produce even cleaner images and more natural
textures than the previous α7S II model, even when shooting in near
Fast Hybrid AF for stills
The Fast Hybrid AF system combines speed
and precision. With 759 focal plane phase-detection sensors and 425
contrast-detection points distributed across most of the image area, the
α7S III quickly finds and tracks your subject throughout the frame.
Outstanding continuous shooting performance
Use your choice of mechanical or electronic
shutter for continuous burst shooting, with AF/AE tracking, at up to 10
fps. Capture decisive moments with over 1,000 frames of continuous
uncompressed RAW shooting possible
Highly sensitive AF for low-light focusing
AF algorithm advances have allowed the α7S
III to achieve autofocus in lighting conditions as dim as EV-6, where
subjects are barely even visible with the naked eye.
Still-image quality advances through new sensor and engine
The newly developed image sensor and image
processing engine deliver improvements in colour reproduction,
particularly of skin tones, and texture depiction in still images.
New HEIF format and HLG image capture modes
The HEIF image file format is supported,
offering better image quality and greater compression efficiency than
JPEG, plus 10-bit colour. High Dynamic Range still images can also be
captured in HLG mode for viewing on compatible TVs.
Two CFexpress Type A-compatible media slots
Both card slots support both ultra-fast
CFexpress Type A cards, allowing high-bitrate recording and fast buffer
clearance, and SDXC UHS-II cards. Parallel and Relay recording are also
