Canon 5D Mark III Video ISO Test Preview Pt. 1 of 3

Over the past few years, the Canon EOS 5D Mark II has been a run-away hit with independent filmmakers. It was one of the first DSLRs to offer 1080p High Definition video, allowing it to compete alongside more expensive, traditional camcorders.

Now, four years later, the new Canon EOS 5D Mark III has arrived and thankfully it hosts some upgrades to the video mode. With the more powerful DIGIC 5+ processor, moiré is reduced and the rolling shutter problems minimized. On the software side, encoding is more advanced, giving you options to record in a new, higher quality ‘All-i’ compression.

  • Moiré: When shooting a video that contains areas of repetitive detail, if it exceeds the resolution of the camera it will create a wavy moiré pattern or haze like artifacts.
  • Rolling Shutter: When shooting video on a DSLR, different portions of the frame are exposed at different times in relation to the other portions. When the subject or the camera moves during exposure, the result is reflected in the frame as either skew, wobble, or partial exposure. This distorts your image and hurts the quality.

The 5D Mark III’s 35mm full frame sensor allows for shallow depth of field and relatively sharp picture quality. You also have full manual control over the way your video looks, controlling shutter speed, ISO, and more.

  • ISO: The measure of a digital camera sensor’s sensitivity to light. This effects the amount of noise and grain present in your video.

To determine the amount of noise present in each ISO setting, we created a series of tests on 5D Mark III’s sensitivity. For those of you who haven’t seen the results watch the video above.

1. First Impressions: After reviewing the footage for the first time, we had a near impossible time seeing any noise below 20000 ISO.

2. Results: Once we bumped up our levels and zoomed in 200%, we started to see that there is was at least some grain present in each ISO setting.

3. Conclusions: Native ISO numbers faired the best with 160, 320, 640, and 1250 showing the least amount of noise. Not that the other settings are bad, but I recommend avoiding them. ISO up to 6400 is usable but again stick with the native ISO numbers.

More Canon 5D Mark II ISO video tests are coming soon, this time showing the noise levels with the Noise Reduction feature turned on (Normal & High).
