Sony A7III Mirrorless Camera

Sony’s remarkable A7 III Mirrorless camera is a game-changer for professional photographers and cinematographers. The Sony Alpha a7 III’s 35mm full-frame Back-illuminated BSI CMOS sensor produces exceptional images with superb colour. It’s one of the reasons why this camera is the best selling model out of all mirrorless cameras.

Featuring the newly developed BIONZ X Image Processor, the Sony A7III is equipped with a fast read and write speed to its dual card slots making 4K video a breeze. Plus, with 10 FPS continuous shooting and a focal-plane phase-detection AF, there are no stopping photographers from capturing incredible wildlife and sports photos. It’s all thanks to an award-winning high-resolution full-frame image sensor.

Sony Alpha a7 III Professional Design for Handheld Operation

As a compact body, the A7 III follows the prior a7 II in design aesthetics. As a lightweight and compact camera body, it’s ideal for rigs and cages in the cinematography world. However, if you are more prone to stills, we recommend the optional VG-C3EM vertical grip, especially using longer focal length E-mount lenses. Aside from either of these configurations, you’ll find picking up the camera with one hand a pleasurable experience. Button ergonomics are well thought out (such as the MENU button, navigation controls and focus magnifier), and you’ll find the improved menu is a plus for anyone new coming into the Sony system.

Superb Quality From a Full-Frame Image Sensor

Professional tools require the ultimate quality, and in the case of the Sony Alpha a7 III, it delivers in spades! The best quality is the 35mm full-frame sensor and the newly developed BIONZ X Image Processor. Both work in tandem to produce excellent results. As light hits the sensor through an E-mount lens, it’s processed as a series as 1’s and 0’s at super-fast speeds. After processing, photos and videos are saved to either one of the two memory cards or an external recorder.

What makes this full-frame sensor brilliant is its development over time. Previous models in the a7 series have been refined to ensure colour science and quality are better than the last. The result is a higher image resolution and images that can offer a larger dynamic range (perfect for instant HDR workflow). The attention to improvement makes the Sony A7 III Mirrorless camera the most popular mirrorless camera body in today’s market.

4K 60p Uninterrupted Recording on the Sony A7III

Sony’s belief in revolutionising the cinema world is unmatched by any other brand. While others focus on the photography element, Sony adopts a philosophy to incorporate video features in the Sony Alpha a7 III. Take, for instance, 4K movies; most brands offer a 4K solution, but the frame rate and codec differ. Sony’s UHD 4K video can record at 30 fps, but it’s the 2.4x oversampling that can render out greater detail than most cameras. The 35mm full-frame sensor can do a full pixel readout, ensuring pixel binning is void. After processing from the back-illuminated BSI CMOS sensor, the resulting 4K movies are higher in quality with reduced aliasing and moire.

Aside from this movie recording magic, the pro camera body can record up to 120 fps in Full HD (in a 100 Mb/s XAVC S format) with 4:2:0 sampling. There’s also the option to record externally with 4:2:2 sampling to an external recorder such as an Atomos Ninja V+.

AI Autofocus

Intelligent focus is about rewriting the rules. What may have worked on a previous model needs improvement, and that’s exactly what’s happened on the Sony Alpha a7 III. Now using a focal-plane phase-detection AF, 627 points to be exact, the camera body can navigate any focus pitfalls. This fast hybrid AF system combines 425 contrast AF points making it unstoppable in all lighting environments, from candlelight through to the middle of the day.

Such an incredible focus system works parallel with the 5-Axis steady shot inside to ensure all E-Mount lenses are stabilized for still and movie recording. There’s also another trip up its sleeve – 4D focus technology. Sony explains this by combining as many focus points as needed to gain and maintain focus.

Sony A7III’s Anti-Dust System and Weather-Sealed Body Design

Mirrorless cameras offer brilliant image quality until they meet their kryptonite – dust. Dust in cameras is an ongoing problem when particles reside on a sensor, leading to images’ artefacts. To prevent this, the Sony A7III camera body utilizes a special filter at the front of the imaging sensor. Using ultrasonic vibrations (70,000 cycles per second), dust and particles are removed every time you turn on and off the camera.

The Sony A7III is made for taking out in the field due to high-quality weather-sealing resistant to dust and moisture. The lens mount is improved, making it more sturdy for longer, heavier lenses. All major buttons and dials surrounding the outside of the camera feature weather seals.

Tough Construction

There’s something comforting knowing that a tough magnesium alloy chassis surrounds the full-frame image sensor. With solid construction, the camera warrants being taken on any journey you put in front of it. Within the popular a7 III mirrorless camera, you’ll find weather sealing across all ports, including where the NP-FZ100 battery is located, making it usable in environments where dust and moisture could be an issue. All in all, with an impressive build, the a73 is a camera you can rely on.

Sony a7 III’s Connectivity

Sony’s attention to detail has been paramount in this mirrorless camera’s success. The A 7III camera body features state-of-the-art connectivity for both E-mount lenses and accessories. Cinematographers, you don’t have to rely on the built-in stereo microphone as there’s an external microphone input (3.5mm) for a Rode Videomic Pro R or a similar calibre microphone. You can also monitor audio recordings directly from the camera when plugging in headphones using the 3.5mm headphone jack. Connecting to an external monitor is easy as plugging in the HDMI D (Micro) cable.

Photographers can also find some handy connectivity tools on the camera. Wi-Fi and Bluetooth connectivity seamlessly work in transferring jpeg images or controlling the camera remotely. NFC (Near Field Communication) is also supported, allowing a one-touch connection between the camera and compatible mobile devices; no complex setup is required. Once connected, the linked mobile device can also display a live view image on its screen and remotely control the camera’s shutter.

Improved Battery Performance

Like the Sony A9 III, the A7III is powered by the common Z-Series NP-FZ100 battery, which provides a battery life of around 710 photos. This makes the battery life 2.2x the capacity of the previous model. If you already have the QZ1 battery charger or VG-C3EM vertical grip for the camera body, you’ll find the Sony battery is compatible. We would suggest carrying a spare battery as you will only get one in the box.

Customizable Menu

If you use your camera a particular way, then the Sony Alpha a7 iii has you covered. With an array of customizable buttons, users can program in their favourite settings with ease. This all comes from extensive feedback from the user community and limits the need for deep menu dives to find a simple setting.

Dual Card Slots

Housed inside the camera are dual card slots which support two SD cards. The saving or backup customization is outstanding. Users can opt to either save photos on one memory card and videos on the other. Alternatively, there’s also an option for overflow recording or backup. If you plan to record 4K movies for longer durations, we would recommend bypassing the dual slots as only one of them is UHS-II compatible. Sony encourages recording to an external recorder/monitor in this use case. This way, you will be able only to use the SD memory cards as a last resort backup.

Why Buy the Sony a7 III?

Overall we think the Sony a7 III mirrorless camera is a winning combination of quality and durability. Featuring a high-resolution full-frame image sensor and newly developed BIONZ image processor, images from this camera save quickly and appear sharp with excellent dynamic range. The strengthened e-mount supports longer e-mount lenses for sports and wildlife photographers, making it ideal for capturing photos at 10 fps continuous shooting. Cinematographers will fall in love with the Sony A7III’s 35mm full-frame sensor, fast hybrid AF system, 5-Axis steady shot inside stabilizer and 4K video.

If you plan to upgrade from a previous model, you’ll find the Sony a7 III will fulfil all your needs. All you’ll need is a fully charged battery and memory card to get going.
