In professional photojournalist Nick Didlick’s recent blog post he teams up with Harry Kaufmann, the founder and president of Beachtek, to test out the audio quality of the Sony α7 III compared to other cameras. Using an Audio Precision APx515 Audio Analyzer, Kaufman checks the THD+N, signal-to-noise ratio, and frequency response, and he was surprised by the clear results.
“The Sony cameras came out on top. All three models had virtually identical results (I also included an α9 II and an α7R IV to see if there was a difference in the Sony camera line-up). They had very low noise levels, and what surprised me the most was how wide the frequency response was. Usually, these types of cameras are only suitable for recording voice as they have a rather narrow response curve. They would not do well for recording music as there is very little bass response. However, Sony’s were flat to almost 20Hz, so they would be ideal for recording even the highest quality orchestra music – with a good mic, of course”.
“In summary, the Sony’s are the clear winners with their excellent low noise performance, low distortion, and incredibly wide frequency response. In fact, they are the best cameras I have ever tested.”
