Sony Alpha 7S III (ILCE-7SM3) Body + Sigma 35mm f/1.4 DG DN 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.

In addition to 2.4 GHz connectivity, Wi-Fi® connectivity at 5 GHz is also provided for remote operation, wireless preview, and faster, more stable data transfer of photos and videos.

LAN cable connection

A USB Ethernet adapter cable can be used to establish a 1000BASE-T LAN cable connection via the camera's USB Type-C® port in complex, interference-prone environments or for higher bandwidth requirements.

Remote preview and recording

Wired and wireless remote recording via PC or mobile devices is possible with Imaging Edge ^MobileTM for efficient workflows and recording in demanding conditions.

Superior optical performance and handling improvements bring one of the most popular focal lengths up to date. With the 35mm F1.4 DG DN | Art, SIGMA has reinterpreted a popular subject and modernized it with a design calculated for mirrorless systems and all the latest SIGMA technologies.

The existing 35mm F1.4 DG HSM | Art was SIGMA's first GLOBAL VISION lens.
When it was launched in 2012, it set the standard for all subsequent lenses in the Art range, and thanks to its outstanding image quality, it remains the first choice for many professional photographers to this day. Nine years on, the 35mm F1.4 has now been redesigned from the ground up in a version for mirrorless cameras. This new development culminates the lens development skills and advanced manufacturing techniques SIGMA has added over the past decade. Like all SIGMA lenses, the 35mm F1.4 DG DN | Art is produced entirely at the company's factory in Aizu, Japan, where the highest level of optomechanical mastery is assured.

At the heart of the design of the 35mm F1.4 DG DN | Art was an optical calculus at the highest level of its class.
Although it remains significantly smaller and lighter than the existing 35mm F1.4, on the one hand it draws sharply to the corners of the image even at open aperture, and on the other hand it produces a creamy background bokeh; all aberrations are well corrected.

The 35mm F1.4 DG DN | Art is light enough to form a well-balanced combination with a compact mirrorless camera.
Nevertheless, it comes with many professional features, such as an extremely fast autofocus, an aperture ring with disengageable detent and an option for locking in automatic or manual mode, as well as a configurable AFL button. This makes it just as suitable for professional use as it is as an always-on lens for occasional outings, and it lends itself to video recording as well as photography.

For SIGMA, the 35mm F1.4 DG DN | Art is the new gold standard for fast 35mm fixed focal lengths.

Key features:
1. Outstanding imaging performance with compact dimensions
The most important design goal in the development of the 35mm F1.4 DG DN | Art, as with all lenses in the Art series, was outstanding imaging performance. Fifteen optical elements in 11 groups are responsible for this performance. The correction of color errors caused by the different refraction of light depending on the wavelength (the so-called dispersion) is achieved by two lenses with particularly low dispersion (SLD = Special Low Dispersion), one lens with extremely low dispersion (ELD = Extraordinary Low Dispersion), one lens with fluorite glass-like dispersion (FLD = "F" Low Dispersion) and two aspheres. The combined effect of the optical design and the special types of glass results in an effective reduction of all aberrations, including chromatic aberration, which cannot be corrected in the camera after the fact.

Despite the high F1.4 speed, the coma itself remains low at open aperture, which recommends the Lens for astrophotographers - this tail-like distortion of bright points of light would be particularly distracting in photographs of the starry sky.

Due to the 11 rounded aperture blades, which ensure rounded out-of-focus circles even when stopped down, the bokeh always remains pleasantly soft and makes the sharply imaged subject plane stand out all the better. In backlit situations, SIGMA's stray light and ghosting prevention technologies prevent misdirected light rays from compromising contrast in adverse lighting conditions.

2. Fast and quiet autofocus
Only a single lens element is moved by a stepper motor to focus the SIGMA 35mm F1.4 DG DN | Art. The low mass of the focusing element allows it to respond quickly, quietly and without delay to any desired change in focus, enabling smooth tracking of focus on moving subjects. Manual focus is precise, but the focus ring also exhibits the resistance needed for smooth, jerk-free focus shifts when shooting video. Of course, the focus mode can be switched directly with a slider on the Lens.

3. Professional features
The aperture of the SIGMA 35mm F1.4 DG DN | Art is controlled by an aperture ring - or by the camera's automatic system if the aperture ring is set to the "A" automatic setting. Either way, a lock prevents you from inadvertently switching between automatic and manual modes. Especially for videographers, there is an option to turn off the aperture lock, which allows for continuous exposure control via aperture. The AFL button can be configured in its function via the camera menu, provided that the camera model used supports this. Like the slider for selecting the focus mode, the AFL button is ergonomically positioned for easy operation with the thumb.

The scope of delivery includes a tulip-shaped lens hood that effectively reduces stray light. The lens hood has a locking mechanism for secure attachment to the Lens. Thanks to a rubber coating, it has a good grip and it is quick and easy to attach and detach.

In use, the 35mm F1.4 DG DN | Art proves to be exceptionally robust, so that it can withstand professional use without any problems. The splash-proof and dust-proof construction with seals on all controls and the interfaces of moving parts as well as a sealing lip on the bayonet protects the Lens against the elements, and the water- and oil-repellent coating on the front lens ensures that imaging performance remains undiminished even under adverse conditions.
