On paper, we find here a completely new sensor in resolution 12.1 megapixels From the Exmor R series, when it works together with the latest image processor BIONZ XR, which brings to the array 8 times more processing power than its predecessor. Sony is also showing a significant reduction in the rolling shutter effect, so that when filming in motion we will encounter less of the familiar wave motion and a sharper and more stable transition between frames.

The focus segment has been significantly upgraded, with the new generation Sony using a drastically faster hybrid focus than the previous generation, with the sensor on 759 focus points Automatic that covers 92 percent of its size. However, there are also 425 Contrast points spread over a smaller part of the sensor, with Sony allowing 10 frames per second with active autofocus, but while the number mentioned is not very large, up to 1000 unprocessed RAW images can be sent to wait until That it will be filled.
In order to allow fast and accurate focusing even in dark lighting conditions, Sony uses artificial intelligence when using Real-time Eye AF technology to identify the subject’s face even when their face is covered. In numbers, the eye-tracking focus performance has been improved by 30 percent, so now the camera should continuously monitor the user’s face even when shooting at low aperture developers and in difficult lighting conditions up to the EV-6 lighting level.
Also in the stills section, Sony enables HEIF format photography so that we can enjoy a smaller and more economical image size than JPEG while getting a wider dynamic range (HLG) and a 10-bit color gamut. The rear touchscreen comes in a 2.95-inch size, with 1.44 million dots, an LCD panel and full-rotation support for the side and turning both the photographer and the photographer side. In addition, you can view the images through the EVF viewfinder which now comes with a resolution of 9.43 million dots with a magnification of 0.9x, a viewing angle of 41 degrees and Sony indicates that it is The brightest viewfinder in the world on camera.
The highlight of the Sony A7S series is the video segment, with this series Sony takes care to allow as many options as possible for the user who wants to create the best video. As a result, Sony allows in the new generation filming in 4K resolution at a rate of 120 frames per second with a color depth of 4: 2: 2. In addition, we will be able to enjoy the film in a 10-bit color range with a color sample at 4: 2: 2 so that we get a much wider spectrum for playing with the colors in the subsequent editing.
With the new generation Sony adds support for the so-called mode All-Intra Powered by the new support for the XAVC SI 4K format, which allows for high-frame shooting as the camera captures and encodes each frame individually at a rate of 600 megabytes per second. In order to use and enjoy the new mode, the camera must use the CFExpress cards we will talk about later and not the standard UHS-II memory card.
In order to create higher quality videos while keeping the file size as small as possible, Sony is switching to the XAVC HS format which uses HEVC / H.265 encoding in order to achieve up to 2 times the file size savings compared to the AVC / H encoder .264. Sony also allows access to the S-Gamut, S-Gamut3 and S-Gamut3.Cine shooting modes that offer a smoother transition in the transition between the shadows and the gray area, so that we finally get a dynamic range of up to 15 stops.
Focus is the main thing when shooting a video, and here Sony offers us access to 7 different speed stages of focus transitions along with a choice between 5 stages of camera sensitivity for switching between objects. Yet, Sony allows indefinite filming in 4K resolution At a rate of 24 or 30 frames per second, while filming at 60 frames per second will lead us to a time limit of a full hour and filming at 120 frames per second will limit us to half an hour.
Body and interface
The new camera body is more durable than ever, with Sony adding a range of enhancements to every possible aperture so that the camera can withstand harsh humidity and dust conditions. In fact, the company has added a number of additional gaskets to the camera body, as well as to the battery structure and memory card section which has been redesigned to withstand harsh outdoor conditions. Also added to the sensor is an ultrasonic sensor that operates at a rate of 70,000 revolutions per second to remove dust from the sensor, with the camera body made of a magnesium mixture similar to other flagship cameras on the market.
Inside the camera we can find built-in stabilization (IBIS) in 5 axes, which allows us, on paper, to continue filming even without using the gimbal and enjoy more stable results while using the Active Mode. Next to the stabilization is one of the camera’s highlights, and this is the new heat dissipation system that Sony has implemented in the camera in the form of a number of heat diffusers that allow 5 times more effective heat dissipation.
Still in the body of the camera, Sony has moved the film button to the top of the camera after receiving reviews from users about its less convenient location in the previous generation. In the left part of the camera can be found for the first time Full size HDMI connector Allows you to transfer 16-bit unprocessed photos and videos to an external recorder.
In the interface section, Sony continues to listen to users and changes the design of the familiar interface to a more colorful and accessible interface for users, so that it will be easy and simple to get to the variety of options found in the busy menu more quickly. In addition, Sony has improved the use of the touch screen so that we can use the main menu via touch and control the display of images via smoothing and the Pinch-to-Zoom ability to zoom back.
The connectivity section now has support for connecting to 5 GHz Wi-Fi, compared to using only 2.4 GHz so far. If you want an even faster connection, you can connect a full Ethernet cable through an adapter that connects to the Type-C connector on the camera. To view what the camera sees from a distance, you can use the Imaging Edge application for your smartphone or computer.
In order to store all the information, Sony offers users access to no less than 4 memory cards, with two inputs being able to support maximum UHS-II cards and the other pair of inputs supporting card entry CFExpress Type-A. To enable this, Sony uses Type-A CFE cards that offer a compact size but slightly compromise on speed while still being based on the 3rd generation PCI Express structure and NVMe 1.3 technology, but include only one information path Allowing up to 1000 MB per second.
Availability and price
The Sony A7S III will be available starting in September for a price tag of $ 3499 For body only.
