We are very proud of how the critical features that enthusiasts and professionals desire have been delivered, and are very excited to see what our creators will produce with the Alpha 7S III.”
The system architecture for the new Alpha 7S III has been completely redesigned to deliver exceptional video and still shooting performance. The new 35mm full-frame 12.1MP (approx., effective) back-illuminated Exmor R CMOS image sensor reduces rolling shutter by up to three times and utilises a variety of advanced light-gathering techniques to ensure high-sensitivity with low noise, allowing users to shoot in low-light situations without needing large-scale lighting setups. In addition to improved image quality, this new image sensor includes a focal plane phase-detection AF system for the first time in an S-series camera. To complement the new sensor, the Alpha 7S III also includes a new BIONZ XR image processing engine that provides up to eight times more processing power, minimises processing latency, and enables many of the hallmark still and imaging features of the camera. The new system also includes the world’s brightest and largest 9.44 million-dot (approx.) OLED electronic eye-level viewfinder and is the world’s first camera with dual CFexpress Type A card slots, enabling high-speed data transfer in a compact size.
The Alpha 7S III offers in-camera 4K recording up to 120 frames per second, 10-bit depth and 4:2:2 colour sampling, producing stunning video recording. The new camera offers a more flexible and efficient post-production workflow with a variety of advanced movie recording modes such as All-Intra and MPEG-H HEVC/H.265 coding (XAVC HS). The Alpha 7S III makes it easy to integrate video recordings with other professional camcorders by providing three colour gamut settings S-Gamut, S-Gamut3, and S-Gamut3.Cine, allowing users to easily match footage shot on the Alpha 7S III with footage shot on the professional camcorders simplifying multi-camera post-production workflow. In addition to S-Log3 gamma curves, the Alpha 7S III supports an HLG (Hybrid Log-Gamma) picture profile with minimum post-production. The Alpha 7S III also allows up to 4K 60p 16-bit RAW output to an external recorder via HDMI Type-A connector, offering additional post-production flexibility.
The new CMOS image sensor and BIONZ XR image processing engine in the Alpha 7S III delivers legendary S-series sensitivity with significantly enhanced colour reproduction and texture renderings for improved overall image quality. The base ISO has been lowered to 80, resulting in a normal range of 80-102,400 (expandable to 80-409,600 for video and 40-409,600 for stills) to provide more flexible ISO plus wide dynamic range with low noise at all settings. It offers improved image quality by approximately 1 stop of noise reduction in the middle and high sensitivity ranges.
The colours and textures of foliage, human skin, and more are ideally and consistently reproduced without dependence on light sources. Gradation rendering has also been refined for better-looking skin tones and highlight roll-off in portraits. It also improves AWB (Auto White Balance) performance with a new “Visible light + IR Sensor” that helps to achieve more precise white balance under artificial lighting, including fluorescent and LED lights.
For the first time in an Alpha 7S series camera, the Alpha 7S III offers Fast Hybrid AF by combining phase-detection and contrast-detection AF, giving it the ability to track subjects over a wide area with outstanding speed, precision and smoothness, even when using a narrow depth of field. Fine focus expression is possible with Sony’s E-mount lenses.
For environments with a lot of movement, Real-time Tracking and Real-time Eye AF are available to maintain constant focus on the intended subject. Sony’s advanced Real-time Eye AF improves detection performance by 30% over the previous system, thanks to the new image-processing engine. It ensures accurate, reliable detection, even when the subject’s face looks away. Real-time Tracking is initiated simply by touching the subject on the screen. Real-time Eye AF is automatically initiated when an eye is detected.
Based on customer feedback, the camera includes several AF features for professional users including AF Transition Speed in seven settings, to easily create rack-focus transitions, and five AF Subject Shift Sensitivity settings, which allows the user to customise how easily AF will switch or stay with the locked-on subject. Touch Tracking allows user to not only initiate Real-time Tracking, but also compose and shoot while using a gimbal or while shooting solo. It’s now possible to Touch Focus during manual focus mode on the LCD screen or remotely from the Imaging Edge Mobile application.
The Alpha 7S III’s design has been updated to ensure effective heat dissipation and minimises overheating — even during extended continuous recording sessions at 4K 60p 10-bit 4:2:2 video lasting an hour or more. A newly developed unique heat-dissipating structure keeps the image sensor and image processing engine temperatures within their normal operating ranges, preventing overheating while maintaining compact body dimensions. The new heat-dissipating structure requires no fan or cabinet vents allowing Alpha 7S III to maintain dust and moisture resistance.
For video on-the-go, the Alpha 7S III is the first Alpha series camera to include Active Modeix with 5-axis in-body image stabilisation to support especially difficult handheld movie shooting. It is also the first Alpha series E-mount body to feature a side-opening vari-angle rear screen, perfect for gimbal-mounted shots, complicated angles, handheld operation and more. The screen rotates sideways, up and down, and features a 3.0 type 1.44 million-dot (approx.) touch panel LCD monitor, for optimal visibility even in bright outdoor environments.
In addition, the Alpha 7S III provides a selection of ten new customisable presets via the Creative Look feature which creates interesting moods for both photo and video shoots.
A digital audio interface has been added to the camera’s Multi Interface (MI) Shoe for clearer audio recordings from a compatible Sony external microphone. Used with Sony’s XLR-K3M XLR Adaptor Kit, the Alpha 7S III provides 4-channel 24-bit digital audio recording capability in an Alpha series camera for the first time. Like other MI shoe accessories, no cables or batteries are required, providing unrestrained freedom for Alpha system moviemaking.
Additional movie assist functions include a redesigned monitor display with a bold, clearly visible red frame that makes it clear when recording is in progress even when mounted on a rig or gimbal, custom zoom settings, adjustable white balance while recording, display rotation, interval recording, still extraction from movies and more.
The Alpha 7S III includes a fast Hybrid AF system with a 759 phase-detection covering 92% of the image sensor. The camera can also achieve high AF precision to accurately and reliably focus in light down to EV-6, where subjects are difficult to see clearly even with the naked eye. Users can continuously shoot more than 1,000 uncompressed RAWxii images at up to 10fps, or up to 8fps in live view mode, with either the mechanical or electronic shutter.
The Alpha 7S III also includes the world’s first 9.44 million-dot (approx.), 0.64 type Quad-XGA electronic viewfinder with a high-definition OLED display. The Alpha 7S III viewfinder offers a 0.90x viewfinder magnification, 41° diagonal field of view, 25mm high eyepoint for clear, low-distortion corner to corner viewing. It is also dust, fog and moisture resistant, extremely responsive, and has switchable modes for different subject types. Every aspect of the Alpha 7S III viewfinder has been designed and refined for a professional workflow.
For the first time in one of Sony’s digital cameras, the Alpha 7S III includes HEIF (High Efficiency Image File Format) allowing for smooth 10-bit gradations and advanced compression technology to maintain image quality while significantly reducing file size and saving storage space. HEIF stills shot in this mode can be played back on a compatible Sony HDR (HLG) TV via a direct HDMI Type-A connection from the Alpha 7S III, delivering true-to-life dynamic range.
The Alpha 7S III features two CFexpress Type A compatible media slots which also support UHS-I and UHS-II SDXC/SDHC cards, enabling high write-and-read speeds while keeping the camera body compact in size. CFexpress Type A cards are ideally suited to high-speed continuous RAW still image shooting as well as 4K 120pi movie recording at high bit rates, providing next-generation write speeds that can quickly clear the buffers of cameras that generate high volumes of still image and movie data. High-speed data transfer to a PC is possible at about 1.7 times faster than an SD card. The dual slots can be set to relay mode for extended continuous recording of even the highest bit rate data as well as simultaneous recording and sort by format type recording.
Professional users need more than just refined features and performance. They also need the reliability and durability demanded of any professional tool. The Alpha 7S III features a redesigned grip for greater comfort and a secure hold, an improved dust removal feature, plus dust and moisture resistance that maximises reliability in challenging environments. It includes a durable, reliable HDMI Type-A connector, and is the first Alpha series camera to support USB PD (Power Delivery), allowing higher power to be supplied from an external source so that users can continue to record for extended periods with minimal internal battery usage.
The Alpha 7S III has been designed and configured to support photo and video journalists and sports shooters who need to deliver stills or movies as quickly as possible with several advanced connectivity options. The camera supports 5GHz/2.4GHz wireless LAN (IEEE 802.11ac) and offers MIMO (multiple-input and multiple-output) to improve communication quality by using multiple antennas, doubling in speed when compared to the Alpha7R IV. It also carries new USB tethering support. When connected to a 5G (5th generation technology standard for cellular networks) compatible smartphone device via USB cable, it is possible to use 5G network for fast and stable FTP file transfer. USB to high-speed wired LAN connectivity also offers stable and fast FTP transfer for both movies and stills. A USB Type-C connector that supports fast SuperSpeed USB 5Gbps (USB 3.2) data transfer is provided, enabling high-speed PC Remote (tethered) data transfer available for smooth handling of large image files.
The new Alpha 7S III full-frame Interchangeable-lens camera will be available in New Zealand from 1st October 2020 for SRP $6,799.95.
