Article: SONY A7IV VS SONY A7SIII – ISO Test – The Truth about filming in Low Light

What’s up everyone today he wants to discuss low-light capabilities between the a74 and the a7 s3. This is not one of those in-depth tests, it is more of an opinionated video after some testing based on what he feels like he would use it for. He wants to share this information with all YouTube producers out there.

Low-Light Performance Comparison

He hears a lot of people saying that the a74 in terms of usable low-light performance is better than the a7 s3 in practical low-light performance. However, in his opinion, the a7s iii is still the better practical low-light camera, especially if shooting in s-log 3.

Real-Use ISO Testing

Real-use ISO performance in crop mode is going to suffer compared to full-frame. When shooting in low-light situations at wedding receptions and other events, it’s important to consider practical low-light performance for run-and-gun shooters and wedding filmmakers.

He found that the a7 4 does not perform as well as the a7s iii in s-log 3 at 3200 ISO, which is when the dual native ISO kicks in for the a74. When overexposing by 1.7 to 2 stops on the camera, he needs to get to 12800 ISO, which the a7s3 handles better.


So, in his opinion, the low-light capability of the a74 in practical, real-world situations is still not as good as the a7s 3. He believes the a7s3 is the best performer in low-light overall, regardless of the ISO range being used.

He clarifies that this is his opinion based on his workflow and video production. He hopes this information is helpful for those considering the low-light performance of these cameras.

Until next time, he signs off.
