Sony A7S III sensor review published by DxOMark. Sony A7S III achieves an outstanding overall score of 86 points, with a combination of 23.7 bits color depth, 13.9 EV dynamic range, and 2520 ISO low-light. Overall, the Sony A7S III BSI-CMOS sensor has relatively high maximum color depth, good dynamic range at base (albeit optimized for high ISOs), and low noise at all ISO settings.
With the overall score of 86 points, Sony A7S III has the 53rd position in the database of full-frame 35 mm and MF sensors overall, the 51st place for full-frame 35 mm, and the 17th place for Sony cameras.
“Low-light specialist” .
From the DxOMark conclusion:
“The Sony A7S III leverages a lot of tech from the A7 and A7R models, and its stills credentials are impressive…Although it puts in a strong performance at its lowest ISO settings, with a relatively high maximum dynamic range and maximum color sensitivity, evidently some concessions were made in that regard, as it is at high ISOs where it’s class-leading. In particular, the Sony A7S III sensor has an impressive response between ISO 1600 and ISO 6400, even outperforming rivals using 24 MP BSI CMOS sensors..”
