Sony Alpha 7S III (ILCE-7SM3) + Sigma 24-70mm f/2.8 DG DN II Art

Unlimited possibilities

The S Series opens up a new dimension for full-frame video with its exceedingly high speed and sensitivity with ultra-low noise, wide dynamic range, great focus and extra-solid image stabilization that was previously unthinkable for 4K video. As a result, entirely new creative possibilities await you.

Made for visual innovation

With outstanding full-frame video performance featuring high sensitivity (extended ISO range up to 409600), wide 15-stop dynamic range, 4K 120p, fast and reliable autofocus, and extrasolid image stabilization, the α7S III once again sets new standards for video.

Large pixels for high sensitivity and low noise

Light intensity, wiring, and output have been fundamentally optimized in the new rear-exposed Exmor^RTM 12.1-megapixel CMOS image sensor. The result is doubled readout speeds, excellent image quality across the ISO range, a wide 15-stop dynamic range, and fewer rolling shutter effects. In addition, the sensor offers AF phase detection in the focal plane.

Up to 8 times more powerful BIONZ ^XRTM image processor
(Compared to BIONZ X image processor)

In addition to the new, significantly faster sensor, the BIONZ XR image processor has also been enhanced to offer up to 8 times more processing power. The forward-thinking design delivers faster, high-quality images for outstanding photo and video capture. In addition, the camera's user interface is now significantly more responsive.

Outstanding AF Performance Even at 4K 120p

The new Exmor R full-frame image sensor and revolutionary BIONZ XR image processor deliver fantastic detail in space and time with ultra-precise AF active throughout, as well as great 4K video even at 120 bps or slow motion. The resolution and depth of field that only a full-frame sensor can provide enable spectacular results.

10-bit 4:2:2 shooting

Shoot directly in-camera with outstandingly detailed 10-bit depth and 4:2:2 color sampling that make image composition, post-processing, and compositing much more flexible.

All-Intra encoding capability

In addition to Long GoP, All-Intra encoding is also possible. This encodes images individually at bit rates of up to 600 Mbps, more accurately capturing complex motion when recording to internal or external media and making editing workflows more efficient.

Top quality and smaller files with XAVC HS

The new XAVC HS recording format encodes with HEVC/H.265 twice as efficiently as AVC/H.264 delivering higher quality images at a smaller file size (XAVC HS compatible editing software required).

Sensitivity extended to ISO 409600

The premium sensitivity of this series opens up new dimensions with the extended video ISO range of 80 to 409600 (standard: 80 to 102400). More light intensity and the optimized output of the 12.1 MP full-frame sensor ensure low noise over the entire ISO range and good images even in almost complete darkness.

S-Log3 Gamma, S-Gamut3.Cine like professional equipment

The S-Log3 gamma curve and the S-Gamut3.Cine color spectrum have been adopted from professional camcorders. They increase dynamic range and simplify color matching for smoother post-production.

HLG (Hybrid Log Gamma)

HLG (Hybrid Log Gamma) simplifies HDR production by shooting for HLG-compatible BRAVIA TVs on-camera without complex post-processing and with seamless gradations with 10-bit color depth.

Improved image quality

With the new BIONZ XR image processor, color reproduction, stability under different light sources, natural color gradations and roll-off have been improved, and the rolling shutter effect reduced.

16-Bit RAW HDMI output

For demanding post-processing workflows, 16-bit RAW output is possible via HDMI connection to compatible external recorders (RAW video output is full-frame 4,264 x 2,408 [16:9] data from the image sensor with frame rates of 60p/50p/30p/25p/24p and various color spaces). The camera simultaneously captures XAVC HS 4K, XAVC S 4K, or XAVC S-I 4K, as well as proxy files.

Efficient editing with proxy capture

In-camera HD proxies (8- or 10-bit depth) can be created for high-bitrate 4K video. The smaller proxy files reduce computer load during editing, speeding up workflow before final 4K delivery.

Fast, accurate, reliable hybrid autofocus

AF with intelligent tracking and sensor-integrated phase detection covers a wide area of the frame. This maximizes ultra-accurate and reliable AF performance when combined with high-quality E-mount Lenses, even when shooting 4K subjects in motion at shallow depth of field and at frame rates of 120p.

Powerful Focus Control for Single Photographers

With 7-stop AF transition speed and 5-stop AF subject switching sensitivity, you can better realize your creative vision when changing focus. AF can be temporarily activated simply by touching it, even in manual focus.

Real-time eye-tracking AF

Real-time eye-tracking AF uses AI for ultra-precise eye focus and is now 30% better in profile or at partial face occlusion (Compared to models with BIONZ X. Sony's internal measurement.). Eye tracking lets you focus on composition even when depth of field is shallow.

Real-time tracking with intuitive touch operation

Real-time tracking analyzes subject color, pattern, depth, and face data for reliable tracking. Touch tracking intuitively and automatically tracks the subject you touch on the LCD.

5-axis image stabilization built into the Body

Ultra-precise image stabilizer and gyro sensor provide 5-axis image stabilization.

Active mode for handheld shooting

Active mode enhances stabilization for video shooting. For unchanged high image quality, the BIONZ XR image processor precisely measures camera shake and optically compensates for it. This allows for handheld stable video in 4K resolution, even while walking or when a gimbal cannot be used due to lack of space.

Digital audio interface for clear audio

A digital audio interface complements the Multi Interface shoe for direct 24-bit inputs. Possible settings are 48 kHz/16 bit 2-channel and, with the optional XLR-K3M adapter kit, 48 kHz/24 bit 2-channel and 48 kHz/24 bit 4-channel.

Great heat dissipation for high reliability

The image stabilizer incorporates a special Sony sigma-shaped (Σ) graphite heat sink that dissipates heat 5 times more effectively - for longer shooting times without sacrificing image stabilization.

Convenient video shooting

Our pro customers have been asking for a VIDEO button on the top that's easier to operate from different shooting positions - here it is. The mode dial layout and switching speed have also been optimized.

High ISO sensitivity

With its enormous ISO range of 80 to 102400 (expandable to 40 to 409600 for stills), the α7S III opens up a whole new range of creative possibilities. The new image sensor and image processing algorithms render images even clearer and textures even more natural than its predecessor, the α7S II, even when shooting in near darkness.

Fast hybrid autofocus for stills

Hybrid autofocus works quickly and accurately. With 759 focal plane phase-detection sensors and 425 contrast-detection points distributed over nearly the entire image area, the α7S III reliably finds and tracks subjects.

Outstanding continuous shooting performance

Continuous shooting is possible with mechanical or electronic shutter with AF/AE tracking at up to 10 frames per second. Capture fleeting moments with more than 1,000 uncompressed RAW continuous shots (When using a CFexpress Type A memory card).

Ultra-sensitive AF even in low light

With the optimized AF algorithm, the α7S III's autofocus now works even in low light up to EV-6, where subjects are barely visible to the naked eye.

New sensor and processor for higher photo image quality

Image sensor and image processor have been redesigned to improve color reproduction, especially of skin tones, and texture representation in photos.

New HEIF format and HLG image capture modes

The HEIF image file format offers higher image quality and compression efficiency than JPEG - as well as 10-bit color. HDR photos can also be captured in HLG mode for playback on compatible TVs.

Two CFexpress Type A compatible media slots

Both card slots support ultra-fast CFexpress Type A cards for high bit rate recording and fast buffer sharing, as well as SDXC UHS-II cards. Parallel and relay shooting is also possible.

Convenient video shooting with adjustable LCD

The 3.0-inch, 1.44 million-dot touchscreen flips open for flexible positioning and a clear view even when used with a gimbal or rig.

Electronic HD viewfinder with 9.44 million pixels

The resolution, contrast and color reproduction of the new electronic viewfinder are unsurpassed in its class (Sony mirrorless digital camera study July 2020). It also offers world-leading 0.9x viewfinder magnification, a diagonal 41° field of view, and a wide 25mm eye relief.

Enhanced usability

The menu has been restructured based on feedback from professional photographers and videographers. Camera settings are now arranged more intuitively and the camera responds better to changes in settings.

New menu structure

Based on feedback from our most demanding professional customers, we have improved the menu structure. It is now clearer and offers easier menu navigation.

Intuitive touch operation

The menu display can be controlled by touch and playback by swiping and finger zoom. Touch operation during recording has also been improved.

The 24-70mm F2.8 Art has been further developed on all levels:
Optical performance, functionality and portability.
The SIGMA 24-70mm F2.8 DG DN II | Art has been significantly enhanced compared to its predecessor. The most advanced technologies available to SIGMA in design and production have been used.

Compared to its predecessor, the SIGMA 24-70mm F2.8 DG DN II | Art has an improved resolving power over the entire zoom range. It also benefits from functional improvements, such as the newly added aperture ring and the high-speed autofocus with newly developed HLA drive (High-Response Linear Actuator).

In addition, the Lens is approx. 7% smaller and 10% lighter than its predecessor. The new 24-70mm F2.8 II Art is therefore a versatile and powerful tool with which photographers and filmmakers can unleash their creative potential.

Key features:
1.)
Top performance that lives up to the reputation of a top model
The new SIGMA 24-70mm F2.8 DG DN II | Art is the successor to the SIGMA 24-70mm F2.8 DG DN | Art, which is renowned for its high optical performance, and has further improved resolution across the entire zoom range. It delivers the highest image quality even at open aperture and the high speed of F2.8 ensures a soft and harmonious bokeh. The Lens therefore offers maximum performance in almost all shooting situations. The short closest focusing distance further expands the creative possibilities. Flares and ghosting are excellently corrected and focus breathing is largely minimized. This means that the outstanding creative possibilities of this lens can be fully utilized in both photo and video applications.

High optical performance across the entire image and zoom range
The optical design of the lens comprises 6 FLD and 2 SLD glass elements. In addition, 5 aspherical lens elements are used. Aberrations are thus reliably suppressed over the entire zoom range. Sagittal coma flares in particular are well controlled in order to achieve a consistently high resolution right up to the periphery of the image. The effective correction of lateral chromatic aberration means that high-resolution images free of color fringing can be achieved.

Equipped with 5 aspherical lenses
The use of 5 high-precision aspherical lenses enables both high optical performance with minimal aberration correction and a compact optical design. SIGMA's production facility in Aizu, Japan, has the high-precision aspherical molding technology that allows it to produce the thin, highly polarized aspherical lenses required for this purpose. This has led to a higher degree of freedom in optical design.

Excellent close-up capability
The Lens offers an excellent close-up focusing distance of just 17cm in the wide-angle range and a maximum magnification of 1:2.7. These factors create potential for creative close-ups.
Note:
When taking close-ups in the wide-angle range, the lens hood should be removed to avoid touching the subject.

Low susceptibility to flares and ghosting
Flares and ghosting, which impair image quality, have been optimized for all lighting conditions using the latest simulation technology. In addition, a nano-porous and super multi-layer coating has been applied to the front lens to prevent flares and ghosting as far as possible. This enables brilliant, high-contrast images to be taken even in unfavorable lighting conditions.

Minimized focus-breathing
The optical design effectively suppresses focus-breathing. The changes in the image angle when focusing are reduced to a minimum, resulting in natural-looking video recordings.

2.)
Betterportability and extended features
The SIGMA 24-70mm F2.8 DG DN II | Art is approx. 7% smaller and 10% lighter than its predecessor. The user-friendliness has been improved with an additional aperture ring and two AFL buttons. Despite its greater compactness and improved features, the Lens offers SIGMA's renowned high build quality. With an uncompromisingly precise and robust construction, as you would expect from a professional photographic tool.

Better handling
While the number of lens elements used has remained the same compared to the previous model, the overall length has been shortened thanks to the modern optical design. In addition, the more efficient mechanical design has resulted in a portable Lens with a maximum diameter of 87.8mm, a length of 120.2mm and a weight of 745g*.
Version with L-mount.

Outstanding processing quality
The robust internal structure and the use of high-precision metal parts ensure high stability and durability in professional use. At the same time, the size and weight of the Lens have been reduced. The design has been consistently geared towards the durability and reliability of the Lens.

Aperture ring with "de-click function"
Many demanding users appreciate the ability to set the aperture directly on the aperture ring of the Lens. The SIGMA 24-70mm F2.8 DG DN II | Art therefore once again offers an aperture ring. Thanks to its "de-click function", this feature is also interesting for filmmakers, as the aperture can be adjusted smoothly and silently in this position. Those who prefer to set the aperture on the camera body can use the aperture ring's lock function and are protected against accidental adjustment.

Equipped with two AFL buttons
Unlike its predecessor, the Lens now has two AFL buttons whose accessibility has been optimized for shooting in portrait and landscape format. These buttons can be assigned individual functions with compatible cameras.

3.)
Professional functions, including high-speed autofocus
The SIGMA 24-70mm F2.8 DG DN II | Art has a high-speed AF with HLA drive in order to offer maximum performance in every shooting situation. Other features, such as dust and splash protection, the water and oil-repellent coating of the front lens and the zoom lock switch complete the professional features of the lens.

With HLA linear actuator
The Lens is equipped with an HLA (High-Response Linear Actuator) linear motor for the
AF drive. Thanks to the powerful HLA, the maximum
drive speed is more than three times that of the previous model*, ensuring
responsive AF shots.
*compared to the maximum drive speed of the SIGMA 24-70mm F2.8 DG DN | Art, the actual AF focusing time may vary

Protected from external influences
In addition to the dust and splash-proof Body*, the front lens
of the Lens has a water and oil-repellent coating. Even
in difficult shooting conditions, you can take pictures without worrying.
* The lens is protected against dust and splash water, but is not waterproof.

Equipped with zoom lock switch
The lens is equipped with a zoom lock switch that locks the lens in the wide-angle range and prevents the tube from extending unintentionally due to its own weight. The lock can be released not only via the switch, but also by turning the zoom ring, which enables flexible handling even for spontaneous shots.

Includes lens hood and case
The specially adapted lens hood LH778-05 is included with the SIGMA 24-70mm F2.8 DG DN II | Art and is securely locked with a quick twist. The Lens is supplied in a matching case for storage and safe transportation.
