Original RRP £1,499 | You Save £500
The Sony a7 III body is a full frame mirrorless camera for professional, enthusiast photographers and videographers alike. It features a newly developed 24.2 megapixel full-frame CMOS back-illuminated sensor for incredible sensitivity and dynamic range. The a7 MKIII also includes improved AF speed, precision and tracking performance with 693 phase-detection AF points and up to 10 frames per second shooting. The ISO can be extended to an amazing 50 to 204800 (stills) and the new battery allows shooting of up to approximately 710 photos. 4K video is also included along with improved Fast Hybrid AF for movie recording. We love this camera for its best in class video performance and excellent all-round application for stills.
Back-illuminated 24.2MP full-frame sensor
The 35mm full-frame Exmor R™ CMOS image sensor features 24.2-megapixel resolution, back illumination, and gapless on-chip lens design for extraordinary sensitivity and dynamic range. Two times faster data readout speed is achieved through copper wires and front-end LSI.
Enhanced image processing system
A combination of new-generation image processing system and a new sensor achieves an up to 1.5-stop improvement12 in image quality. A wide ISO sensitivity range of up to ISO 51200 is standard, and approx. up to 15-stop13 dynamic range at low sensitivity settings is realised. Upgraded Detail Reproduction and Area-specific Noise Reduction join to suppress noise and maintain a sense of high overall resolution. Colour reproduction, especially of skin and nature scenes, has also been dramatically improved. The α7 III also supports 14-bit RAW output even during silent shooting/continuous shooting.
Wider, faster AF performance
An evolved image processing system and α9 camera AF algorithms optimised for the α7 III improve AF speed, precision, and tracking performance. 693 phase-detection AF points and 425 contrast-detection AF points provide high-density wide-area coverage. AF speed improved by up to twice and more precise AF tracking performance let you capture and maintain focus on a quickly moving subject in unpredictable motion. The α7 III also autofocuses reliably down to EV-3 brightness.
New AF-ON button and multi-selector
The new AF-ON button activates autofocus without any half-press-shutter-button focus sequence, so you can concentrate better on exactly when to release the shutter and capture the moment instantly. A multi-selector lets you shift the point of focus quickly and efficiently. You can select and shift the point of focus intuitively, so you won’t miss great chances to shoot moving subjects.
Eye AF now supporting AF-C
Eye AF newly supports AF-C mode with greater precision that dramatically enhances portrait shooting, plus higher AF speed that makes it easier to shoot a portrait of a moving subject, even if the subject looks down and away from the camera, or is backlit with face in partial darkness. The α7 III supports Eye AF for A-mount lenses mounted via an adaptor.
AF tracking sensitivity when shooting stills is adjustable in five steps for subjects that move outside of the focus area. Autofocus areas and points remain the same or change when switching between horizontal and vertical orientations, depending on the shooting situation. AF area registration allows frequently used focus point settings to be memorised and assigned to custom buttons for fast, convenient recall at a touch whenever needed.
Up to 10 fps with AF/AE tracking
With new shutter charge unit and image processing system refinements, the α7 III can shoot continuously at up to 10 fps with AF/AE tracking (up to 8 fps with minimal display lag in live-view continuous shooting mode) for easy, stable shooting of even intensely active subjects. Up to approximately 177 JPEG images (standard) in full resolution, 89 compressed RAW images, or 40 uncompressed RAW images can be captured in one continuous burst. An electronic shutter allows silent, vibration-free shooting of wildlife and other sensitive situations when even slight noise can mean missing an ideal shot.
Flicker from fluorescent and other artificial lighting is automatically detected and shutter action is timed to minimise the flicker’s effect on still images. This suppresses exposure and colour anomalies at the top and bottom of images shot at high shutter speeds, as well as exposure and colour inconsistency between continuous shots, so you can take images indoors with more confidence.
High-resolution full-frame 4K movies24 with full-pixel readout without pixel binning that condenses approximately 2.4 times the amount of data required for 4K movies (QFHD: 3840 x 2160) results in minimal moiré and jaggies. Advanced image processing makes it possible to record full-frame 4K movies with outstanding image quality in the mid-to-high ISO range, so you make the most of the 4K movie format’s unique potential in every shot. Super 35mm can also be selected, instead of full-frame mode, as needed.
Versatile movie recording functions
The α7 III provides a wide array of functions to facilitate workflows of professional videographers, including clean HDMI output, time code / user bits (TC/UB), rec. control, marker display/setting, zebra function, Slow and Quick Motion, simultaneous proxy movie recording, extraction and separate storage of a still from a movie, and Gamma Display Assist function, among others.
Fast Hybrid AF for movie recording
An efficient combination of focal-plane phase-detection AF and contrast-detection AF accurately locks onto even fast-moving subjects, then tracks them smoothly during movie recording. AF coverage for movies extends across an area almost as wide as the AF coverage area for still images, so once the high-density AF system locks onto a movie subject, the camera continues to track it steadily and tenaciously. Three AF drive speed settings give you freedom to use slow focus effects when shooting movie scenes.
In-body 5-axis image stabilisation with 5.0-stop shutter speed
This comprehensive system compensates for five types of camera shake that tend to blur images: pitch/yaw shake when shooting at longer focal lengths; X/Y shake in close-up (including macro) shooting; and roll shake when recording stills at night and movies. It effectively achieves 5.0-stop-faster shutter speed, so the α7 III can take full advantage of its high-quality imaging capability and live-view image performance. Furthermore, it functions with A-mount lenses attached via mount adaptor, as well as E-mount lenses.
Longer battery life
For extended periods of confident shooting, the NP-FZ100 battery has approximately 2.2 times the capacity of a NP-FW50 battery that allows shooting of up to approximately 710 photos with one full charge and an optional VG-C3EM Vertical Grip can hold two batteries. USB Type-C™ and Multi/Micro USB ports allow external mobile batteries to power the camera for extended recording. Even more conveniently, accessories such as a remote control unit can be used via Multi/Micro USB port while power is supplied via USB Type-C™ port. BC-QZ1 optional battery charger allows quicker charging than charging via USB.
Location Information Link via Bluetooth
he camera can be paired with PlayMemories Mobile app installed on a compatible mobile phone or tablet device to acquire location data, record it on still images, and correct camera date/time and location settings. PlayMemories Home application can be used on a personal computer to organise imported still images on a map.
One-touch remote & One-touch sharing
ne-touch remote can turn a smartphone or tablet into a viewfinder/remote control. One-touch sharing transfers photos/videos to your device for SNS sharing. Just install a PlayMemories Mobile app via Wi-Fi to your NFC-enabled Android device, and then touch the device to the camera to connect them. If you don’t have NFC, use QR code compatibility to pair the devices.
Touch screen LCD
3.0-type 922K-dot LCD screen offers touch screen operation and bright, clear, finely detailed views even outdoors. Use Touch Focus to focus instantly on a point that you touch on the screen and Touch Pad to drag the focus frame with a fingertip on the LCD as you monitor the shot through the viewfinder. This LCD tilts up by as much as 107°, and down by as much as 41° for flexible, convenient camera holding and shot monitoring.
High-resolution, high-contrast XGA OLED Tru-Finder
Providing high resolution and contrast, plus the excellent gradation and colour reproduction that are advantages of OLED viewfinders, this approximately 2359K-dot XGA OLED Tru-Finder faithfully depicts images with clear corner-to-corner visibility. Magnification is 0.78x (approx. 38.5° diagonal FOV). ZEISS T* coating greatly reduces obtrusive lens reflection on the ocular lens. Startup is approximately 40% faster than with the α7 II when the camera is switched on. Furthermore, view mode can be set to “High” to provide finer and more natural details by taking maximum advantage of the data read from the 24.2 effective megapixel sensor.
Highly durable and operable in tough conditions
The α7 III functions reliably in challenging environments. Its body is fortified by lightweight, high-rigidity magnesium alloy top cover, front cover, and internal frame. The number of lens mount screws has been increased to six for enhanced durability. Major buttons and dials are sealed. Sealing is provided throughout the body to minimise entry of dust and moisture.
