Review of Nauticam Underwater Housing for New SONY A7S MK III

Sony has done it again: With the A7SIII, a new, outstanding mirrorless high-end camera has been born. Particularly filmmakers will have fun with this camera.

The entire Sony Alpha 7S series is known for its strengths in video recording and low-light performance. The new Alpha 7S III raises the bar even higher. But not only videographers get their money’s worth with this camera …

Sony Alpha 7S III Features

Sony has significantly improved the image quality of the A7SIII. Thanks to the new BIONZ XR processor and the sensor, photos are now even sharper. And they can be processed up to 8 times faster! The resolution of 12 megapixels has remained. The excellent dynamic range of 15 f-stops offers plenty of scope in post-production.

As usual, the camera body is excellently designed. In fact, it’s even better protected against dust and splash water than former camera models. Another highlight is the foldable and rotating display. It helps to read the monitor easily from different angles and perspectives.

The Sony A7SIII scores particularly well in the areas of video and low-light performance. The camera creates 120 frames per second in 4K and up to 240 fps with a resolution of 1920 x 1080 pixels. Additionally, the extremely light-sensitive 12-megapixel sensor enables a very high maximum ISO value.

So nothing stands in the way of endless filming in 4K at a high frame rate. Moreover, you can expect very sharp and crisp results. If you combine the camera with a Ninja V from Atomos, you can even record RAW signals via HDMI of up to 4K in 60p (as 12-bit ProRes RAW!!).
