Sony Alpha A7 III: Features (Detailed)

Sony Alpha A7 III provides some great advantages to its users. Here, we are going to provide its most prominent features in detail.

Robust Magnesium Alloy Body with Dust and Moisture Resistant Design

The A7 III body is backed by a lightweight, powerful magnesium alloy in the interior as well as exterior of the device. Similarly, the grip area has also been strengthened with an attached magnesium alloy front cover. The lens mount’s screws have been increased to six for maximum durability and protection even while using heavy telephoto lenses.

The camera body is completely and perfectly sealed so it remained functional in any kind of weather conditions or environments and doesn’t let enter dust or moisture. Not only this, all major dials and buttons are covered with seals for double protection.

Touch AF Function

With its built-in Touch Focus feature, you can easily define the selected focus point. Not only this, subjects closed to the edges of the frame can be quickly selected without using manual reframes.

When focusing manually, you only need to double-tap any point on the screen for getting a magnified view of that area or object. This is how your Touch AF lets you enjoy extremely flat focus point altering while even making movies. Focusing doesn’t get any better than this.

Enhanced Eye AF with AF-C

Sony Alpha A7 III comes with a highly advanced Eye AF that supports AF-C mode for maximum precision that amazingly enhances portrait shooting like a pro. The higher AF speed makes the device convenient to capture a moving subject’s portrait, no matter subject is away from the camera or not. The Alpha 7 III camera by Sony supports Eye AF for A-mount lenses mounted with the use of an adaptor.

Back-Illuminated 24.2MP BSI All-Around Full-frame Image Sensor

The most advanced 24.2MP back-illuminated Exmor R CMOS image sensor is connected with a front-end LSI of the device, which doubles the readout speed of the image sensor effectively and efficiently.

In addition to that, it has an updated and optimum quality BIONZ X processing engine that can boost processing speed up to 1.8 times approx. than the older Alpha 7 II. Due to this, it gets high sensitivity results with wide 15-stop dynamic range and low-noise performance. It also has the ability to produce spectacular images in 14-bit RAW4 format even when shooting in continuous or silent mode.

Up to 10fps with AF/AE Tracking

The Sony A7 III comprises of a refined image processing system that has the ability to capture full 24.2 Megapixels photographs at up to 10fps with continuous and perfect AF (Autofocus)/AE (Auto Exposure) tracking for up to 177 JPEG Standard photos, 40 uncompressed RAW photos, or 89 compressed RAW photos. This rapid 10 fps mode is available with either an electronic shutter or a mechanical shutter for an entire silent shooting.

Furthermore, the camera can also capture at up to 8 fps consistently in live view mode with minimal lag in the viewfinder or LCD. These super-fast and incredible options let its user capture fast-moving subjects with the highest accuracy and maximum image detail.

The State-of-the-Art Hybrid Autofocus System

The Alpha 7 III Sony Camera comes with a world-class autofocus system that includes 693 focal-plane phase-detection AF points. They have an ability to cover 93 percent of the image area approximately, 425 contrast AF points, and solid Eye-AF.

When combined, both phase and contrast detection AF points make the 4D FOCUS hybrid AF system for fast, wide, and trustworthy AF that stays locked on. This advanced autofocus system provides AF acquisition at almost 1/2 time when compared to the Alpha a7 II in the low-light surrounding with tracking that is approx. 2x more accurate as well. The so-called Eye AF feature is also approx. twice as solid, and can be used while utilising AF-C mode and A-mount lenses with an adapter.

5-Step, 5-Axis In-Body Image Stabilization

The 5-axis in-body SteadyShot image stabilization system has been upgraded precisely to support Hi-Res shooting the feature for an image stabilization system at 5-Step shutter speed. Camera shake is nicely balanced on 5 axis: pitch and yaw, which delivers the biggest overall impact on the quality of the image.

Stabilization is implemented to the live-view image to frame fast-moving subjects efficiently and conveniently. Effective stabilization, stills, and A-mount lenses are great for movies that are attached to a mount adapter.

High-Quality 4K HDR for the Video Professionals

The Sony A7 III is highly capable as a video camera, delivering 4K (3840x2160p) 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 2.4 times of data needed for 4K movies, and then oversamples it to make supreme quality 4K footage with extended depth and detail.

Both S-Log2 and S-Log3 are available for better color grading flexibility, while HLG is included to support quick HDR workflow, allowing High Dynamic Range HLG (Hybrid Log-Gamma) compatible televisions to playback stunning, and natural alike 4K HDR photography.

Best of all, the Alpha A7 III by Sony can also record FHD at 120fps at up to 100 Mbps speed. This way you will get the result to be reviewed and finally edited into 4 times or 5 times slow motion video files in full High Definition resolution. Through an ability to reproduce snaps from deep shadows to piercing highlights, 4K HDR is unmatched.

Highly Powerful and Long-lasting Z Battery

The new Sony Alpha A7 III is loaded with highly powerful and long-lasting rechargeable battery. The high-capacity NP-FZ100 battery has almost 2.2x the capacity of the NP-FW50 W Series camera battery offering the device the biggest-ever battery span of any mirrorless camera, that can capture 710 shots with a single charge.

The battery also supports InfoLITHIUM technology, which allows it to check the remaining battery juice as both a percentage display and 5 step icon on the LCD of this camera.

Our Verdict

With having remarkable still image quality, excellent 4K HDR video, 10fps continuous shooting, comparatively powerful and improved battery life, the Sony Alpha A7 III is an exceptional camera that has acquired attention from many photographers throughout the world, even before its official release. Sony has taken some of the best features and specs from its flagship Alpha A9 and A7R III camera devices and distilled them into a single unique camera that gives an incredible combination of performance and image quality. Though it is little bulky than Mark II, all in all, a very good creation by Sony. And best of all, the flagship Sony Alpha A7 III price is amazing.
