![]() ![]() The A7 III is capable of recording 4K (3840 x 2160) footage to a memory card at 30p/25p and 60Mbps or 100Mbsp. This means you can shoot silently at 10fps if necessary. Furthermore, it’s possible to shoot at 10fps using the mechanical or the electronic shutter. With a fast card installed, the A7 III can shoot at 10fps for 177 Standard jpeg images, 89 compressed raw images or 40 uncompressed raw images. Dropping the rate to 8fps gives a continuous live view feed. As with the A7R III when it shoots at 10fps, there is a brief blackout with the A7 III. Sony has given the A7 III a maximum continuous shooting rate of 10fps. There’s also Sony’s Eye AF mode that helps you target the most important part of a portrait subject. In addition, the system is sensitive down to -3EV, which means it should be effective in low light. This makes it easier than with the A7 II to track moving subjects. These points cover 93% of the imaging area. While the A7 III doesn’t have exactly the same system (that would require the same sensor), it has the same 693-point phase detection points and 425 contrast AF points. The Sony A9’s autofocus (AF) system is phenomenal. Sony A7 III vs Sony A7 II: What are the Key Differences?.It’s claimed to give a 5EV extension in the hand-holdable shutter speed. Sony’s 5-axis optical in-body image stabilisation is on hand. In fact, Sony is claiming a 1.5EV improvement in image quality overall. That indicates that the A7 III should perform well in low light. #SONY A7 III ISO#The sensor and processing engine enable an overall sensitivity range of ISO 50-204,800. In addition, the focus tracking is twice as fast. According to Sony, this results in the focusing in low light being almost twice the speed of the A7 II’s. However, there is a front-end LSI which Sony says doubles the readout speed from the A7 III’s sensor. It also maintains the separation between the A7 Mark III and the 42Mp A7R Mark III and 61Mp A7R IV.Īlthough the A7 III’s sensor is backside-illuminated (BSI), it’s not the same sensor as is in the A9. It gives a nice balance between file size and detail capture. On the basis of one of our recent Twitter polls, I think this a good decision. Sony opted for a 24Mp sensor for the A7 III. ![]()
