ISO & Noise

nanhi · 2015-12-05T16:33:23+0000

There was a recent topic in one of the Canon Photo Forums as follows:- 'Canon cameras have least noise at 100/200/400/800/1600 ISO and not the settings in between'. So this guy was saying that he had a lot of noise at ISO 640 from his Canon 6D. He had posted the photo + a 100% crop. He also mentioned the photo was not tack sharp. Now it is well known that the Canon 6D is renowned for it`s low noise and one wouldn`t expect to see this at ISO 640. So the question and clarification I am seeking is, does Pentax DSLRs, the K-5 & K-3 series, have the same failings as this statement 'Canon cameras have least noise at 100/200/400/800/1600 ISO and not the settings in between'. Thanks

Isn't it also advisable to print at multiples of 1440dpi.... I am sure I saw that somewhere.. It ensures the best quality.

I'm off to drink some beer in FULL PINTS smaller measures aren't as satisfying

Just a couple of caveats. One is that the article was written in 2013, and in two years a lot can change. The other is that it doesn't claim that this is true of all manufacturers, so it may or may not be a current issue and it may or may not apply to Pentax cameras.

Philip's results would seem to suggest that it is not a Pentax issue.

However, to be honest I always use ISO settings of 200, 400, 800 and so on, and always have.
