With outstanding imaging capability and high-speed performance contained in a compact body, the α7 III gives you the power, precision and flexibility to capture once-in-a-lifetime moments just as you like.
Spectacular Full-frame Image Quality
The newly developed 24.2MP back-illuminated Exmor R CMOS image sensor is paired with a front-end LSI that effectively doubles the readout speed of the image sensor, as well as an updated BIONZ X™ processing-engine that boosts processing speed by approximately 1.8 times compared to the α7 II. These powerful components work together to allow the camera to shoot at faster speeds while also enabling its impressive ISO range of 100 - 51200 (expandable to ISO 50 – 204800 for still images) and an overall 1.5-stop improvement in image quality. The camera also features a massive 15-stop dynamic range at low sensitivity settings, ensuring outstanding overall performance at all settings and in all shooting conditions, with significant advancements in accurate colour reproductions of skin tones and the vibrant colours of nature.
Speed to Capture Every Decisive Moment
The new α7 III is equipped with an updated image processing system that allows it to shoot full resolution images at up to 10 fps with continuous, accurate AF/AE tracking for up to 177 Standard JPEG images, 89 compressed RAW images or 40 uncompressed RAW images[xii]. This high speed mode is available with either a mechanical shutter or a completely silent shootingiv, adding to the immense flexibility of the camera. The camera can also shoot continuously at up to 8 fps in live view mode with minimal lag in the viewfinder or LCD screen.
For added convenience, while large groups of burst images are being written to the memory card, many of the cameras key functions are operable, including access to the ‘Fn’ (Function) and ‘Menu’ buttons, image playback and several other menus and parameters including image rating and other functions that facilitate on-location image sorting.
Additionally, if there is fluorescent or artificial lighting present in a shooting environment, users can activate the Anti-flicker function to allow the α7 III to automatically detect frequency of the lighting and time the shutter to minimise its effect on images being captured. This minimises any exposure or colour anomalies that can sometimes occur at the top and bottom of images shot at high shutter speeds.
High Quality 4K Video
The new α7 III is an outstanding video camera as well, offering 4K (3840x2160 pixels) video recording across the full width of the full-frame image sensor. In video mode, the camera uses full pixel readout without pixel binning to collect about 2.4x the amount of data required for 4K movies, and then oversamples it to produce high quality 4K footage with exceptional detail and depth.
An HLG (Hybrid Log-Gamma)[xv] picture profile is available on the α7 III as well, which supports an Instant HDR workflow, allowing HDR (HLG) compatible TV’s to playback beautiful, true-to-life 4K HDR imagery. Further, both S-Log2 and S-Log3 are available for increased colour grading flexibility, as well as Zebra functionality, Gamma Display assist and proxy recording. The camera can also record Full HD at 120 fps at up to 100 Mbps, allowing footage to be reviewed and eventually edited into 4x or 5x slow motion video files in Full HD resolution with AF tracking.
Significant Advances in AF Speed and Performance
The innovative new α7 III full-frame mirrorless camera features a level of AF performance that has been largely improved over the α7 II, including the addition of 4D FOCUS™ capabilities. The new camera has 425 contrast AF points that work with a 693-point focal-plane phase-detection AF system inherited from the acclaimed α9 model. This innovative AF system covers approximately 93% of the frame, ensuring reliable focusing and tracking for even the most difficult to capture subjects.
AF response and tracking has also been greatly improved in the new camera, with almost 2x the focusing speed in low-light condition and 2x the tracking speed compared to the previous model as a result of the faster image sensor readout. This allows complex and unpredictable motion to be captured with far greater precision and accuracy.
The acclaimed Eye AF feature is also available in the new camera, even in AF-C mode, which is extremely useful for situations where the subject is turning around, looking down or otherwise obstructed. It also works when the α7 III is being used with Sony’s A-mount lenses with an optional LA-EA3 adaptor. Additional improvements in focusing flexibility include the addition of a multi-selector or ‘joystick’ for moving focusing points quickly, the addition of touch focusing capability, AF availability in Focus Magnifier mode, an ‘AF On’ button and much more.
