a7 III Full-Frame Mirrorless Interchangeable-Lens Camera Body

Evolutionary leap in image processing power

The a7 III features 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 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-stop dynamic range at low sensitivity settings. This ensures outstanding overall performance at all settings and in all shooting conditions.

Up to 10fps 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 fps 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 fps 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.

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 lenses7 attached via a mount adapter.

6. CIPA standards. Pitch/yaw shake only. Planar T FE 50mm F1.4 ZA lens. Long exposure NR off.

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 RAW 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.

The detail of 4K, the beauty of HDR

4K HDR (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-Log 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 RAW 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 RAW output available even when shooting in silent 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. EVF startup time when the camera is switched on has been decreased by approximately 40% compared to the α7 II.

922K-dot (approx.) 3” (3.0 type) tilting LCD monitor

This large tiltable 3” (3.0 type) LCD monitor features approximately 922K dots for high resolution and detailed viewing. The monitor not only supports touch operation, but tilts upwards by a maximum of 107 degrees and downwards by a maximum of 41 degrees for flexible hold and framing.

Touch AF function

Focusing doesn’t get any more intuitive than this. With Touch Focus you can simply touch the LCD screen to specify the desired focus point. Even subjects near the edges of the frame can be instantly selected without having to reframe or manually shift the focus point. Double-tap any point on the monitor for a magnified view of that area when focusing manually. Touch AF allows smooth focus point changes when shooting movies too.

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 effective, and is available when utilizing AF-C mode and with Sony’s A-mount lenses with an adapter.

Enhanced Eye-AF

Eye AF automatically detects and focuses on the subject’s eye. It has been notably improved in the a7 III, even when shooting a moving subject in continuous AF mode. Face detection has also been updated for higher reliability when the subject is looking away from the camera, when the face is in partial darkness, and other challenging situations.
