If you’ve tinkered around with Canon HDSLRs, then you may have heard that its best to shoot video using sensitivity settings that are multiples of ISO 160. I’ve been doing this because I have heard folks like Shane Hurlbut and Vincent Laforet say for a couple of years now that that’s the way to do it.
Andrew Schär gave us some proof for our eyes in this test with the Canon 60D that he uploaded to Vimeo yesterday. Andrew noted on his Vimeo page the following results of his test:
The results as you can see in the video, are pretty much spot on with what Technicolor has said. Interestingly enough, it seems to me that ISO 640 has about as much noise as ISO 100.
It also seems that ISO multiples of 125 are specifically bad. ISO 1250 is pretty much comparable to IS0 125!
It clearly illustrates that best ISO’s to use for video, starting from lowest noise level to highest are as follows:
160, 320, 640, 100, 200, 400, 800, 1250, 125, 250, 500, 1000, 1600, 2500, 2000, 3200, 4000, 5000, 6400.
Of course, if you’re shooting low-light and you need a high ISO, the best ones to go for would be: 1600, 2500, 3200 & 5000.
If there’s plenty light, keep things on ISO 160.
Multiples of 160 are best, then multiples of 100 and then multiples of 125.
