Video ISO Advice

Here’s an interesting little factoid I stumbled across the other day: Did you know that there’s an ideal ISO at which to shoot video on a Canon EOS 5D camera? The information came courtesy of Vincent Laforet (who is known for being a DSLR video expert) who blogged this quite a while ago, but I guess I’m late to the game on this one. Anyway, here it is: when shooting video on the 5D Mark 2 or Mark 3, be sure to set the ISO to multiples of 160—such as 160, 320, 640, and so on. This is because of the native ISO of the cameras’ sensors, and in practice it means the cameras can actually produce cleaner, lower-noise video files at ISO 320 than it can at ISO 200, better looking files at ISO 640 than at ISO 400. It’s a pretty remarkable accomplishment when you think about it. So if you shoot one of these cameras, try those multiples and see what you think. If you’re not a 5D video shooter, do a bit of testing of your own camera to determine your own camera’s ISO sweet spot. And if you’re interesting in learning more about D-SLR video—or video in general, for that matter—Laforet’s blog is a great place to start.
