The new flagship Canon mirrorless has an impressive spec sheet, even if some questions have been raised over its performance in some of the more cutting edge capacities. The question is, how is the ISO performance when put into testing environments?
The Canon EOS R5 is an impressive piece of kit, there's no doubt about it. One area of its spec that has thoroughly blown me away in the tests I've seen, however, is the ISO performance. In this video, Lindsay Adler goes through a fashion shoot on the streets, at night, and using high ISO to test the noise.
It may be singular to me, but the improvement of ISO performance has been continually outrunning my perceived performance of it. That is, I always expect it to be worse than it is, and I very rarely venture north of 2,000 ISO. I did have to recently and it was a powerful reminder that even cameras a few years old can easily handle that sort of ISO without much of a downside. The new Canon R5 is pushing that even further and I'm honestly stunned at the results in this video. The difference between 8,000 ISO and 2,000 ISO is — for all intents and purposes — non-existent. 12,800 ISO starts to see a softening of details with noise, but it is a long way from unusable and for almost every application, I would be comfortable with that sort of image quality. What really threw me was 20,000 ISO though. That is a number I have never shot at and imagined it would be unusable even in the R5, but it appears to have almost no difference in noise to the 12,800. It wasn't until Adler got to 32,000 ISO that I would consider the image unsuitable for some higher-end uses of it.
What do you make of the ISO performance of the R5?
