Nothing less than spectacular images.

Evolutionary leap in image processing power

The a7 III features a new 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 a7 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 massive 15-stop⁴ dynamic range at low sensitivity settings. This ensures outstanding overall performance at all settings and in all shooting conditions. 

Up to 10fps¹ with Silent⁵ or Mechanical Shutter

The a7 III is equipped with a refined image processing system that allows it to capture full 24.2MP images at up to 10 fps¹ with continuous and accurate AF/AE (autofocus and auto exposure) tracking for up to 177 Standard JPEG images, 89 compressed RAW images or 40 uncompressed RAW images. This high speed 10 fps mode is available with either a mechanical shutter or an electronic shutter for completely silent⁵ shooting. The a7 III can also shoot continuously at up to 8 fps¹ in live view mode with minimal lag in the viewfinder or LCD screen. These high speed options ensure that fast moving subjects can be captured with extreme accuracy and incredible image detail. 

Incredible hybrid autofocus system

The a7 III features a world class autofocus system comprised of 693 focal-plane phase-detection AF points that cover approximately 93% of the image area, 425 contrast AF points and reliable Eye-AF. When combined, both contrast and phase detection AF points form the 4D FOCUS ™ hybrid AF system for wide, fast, reliable AF that locks on and stays locked on. This advanced system delivers AF acquisition in about half the time as the a7 II in low-light conditions with tracking that is approximately 2 times more accurate as well. The acclaimed Eye AF feature is also approximately twice as effective⁴, and is available when utilizing AF-C mode and with Sony’s A-mount lenses⁹ with an adapter.

5-step⁶, 5-axis in-body image stabilization

The 5-axis in-body SteadyShot™ image stabilization system has been fine-tuned to support high-resolution shooting capacity, resulting in an image stabilization system at 5-step⁶ shutter speed advantage. Camera shake is effectively compensated on 5 axes: pitch and yaw that have the largest overall impact on image quality; X and Y shift that is most apparent at high magnification, and roll that can ruin night shots and movies. Stabilization is applied to the live-view image, making it easier to frame fast-moving subjects. Effective stabilization is provided for movies as well as stills, and for A-mount lenses⁹ attached via a mount adapter. 

Secure and versatile dual SD media slots

Two SD media card slots are provided for still and movie storage (one slot for SD cards or Memory Stick) with the lower card slot being UHS-II compatible for fast write speed. Still or movie data can be simultaneously recorded to both cards for backup, or RAW⁴ images can be recorded to one card while JPEG images are recorded to the other. It is also possible to record stills and movies to different cards. Relay recording automatically switches to the second card when the first card is full. Data can be copied between cards while in the camera, for convenient back-up. Sony SF-G series UHS-II SD cards are ideal for situations where maximum transfer speed is required.

High Quality 4K² HDR³ for the Video Professionals

The a7 III is exceptionally capable as a video camera, offering 4K² (3840x2160 pixels) video recording across the full width of the full-frame image sensor. In video mode, the a7 III 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. Both S-Log2 and S-Log3 are available for increased color grading flexibility, while HLG (Hybrid Log-Gamma)³ is included to support an Instant HDR (High Dynamic Range) workflow, allowing HDR (HLG) compatible TV’s to playback beautiful, true-to-life 4K HDR imagery. The a7 III can also record Full HD at 120 fps² at up to 100 Mbps, allowing footage to be reviewed and eventually edited into 4x or 5x slow motion¹¹ video files in Full HD resolution.

The detail of 4K², the beauty of HDR³

4K² HDR³ (High Dynamic Range) astonishes viewers with visual depth and impact that are less like conventional movies and television – and more like real life. With the ability to reproduce images from deep shadows to piercing highlights, 4K High Dynamic Range (HDR) is astonishing. With Instant HDR, the a7 III empowers you to capture High Dynamic Range without complex post production. Hybrid Log-Gamma (HLG) recording captures HDR, yet plays back beautifully on both HDR and conventional televisions. For added versatility, the camera also provides S-Log3 encoding.

16-bit processing and 14-bit RAW⁴ output for natural gradations

Both compressed and uncompressed 14-bit RAW⁴ format are supported. The 14-bit digital signal from the image sensor’s analog to digital (AD) converter is processed in 16-bit form by the front-end LSI and BIONZ X™ image processor before being output as 14-bit RAW⁴ data. The result is smoother, more natural gradations that contribute to higher overall image quality. The enhanced BIONZ X image processing LSI makes 14-bit RAW⁴ output available even when shooting in silent⁵ or continuous mode.

High contrast 2.36-million dot OLED EVF 

The a7 III boasts a high-luminance 2.359 million dots EVF (XGA OLED) Tru-Finder™ which reproduces the finest details, and incorporates legendary ZEISS T* coating to greatly reduce reflections, while the double-sided aspherical element achieves 0.78x magnification with outstanding corner-to- corner clarity.
