Magic Lantern Raw vs H264 on the Canon EOS 5D Mark III

Dave Dugdale of LearningDSLRVideo made the video above that shows where the differences between H264 output and Magic Lantern’s RAW are. A Canon EOS 5D Mark III (price & specs) was used. Dave says:

The real noticeable difference is when you really push and stretch the image, for instance here a shot with both somewhat similar settings and they both looks pretty good, but once you start to add saturation or really push the levels all over the place check out the banding above the mountains and look how the clouds are starting to fall apart image wise.

So you can push the image to make it look like the camera has more perceived dynamic range by stretching it, but even with raw you can only push it so far, but you can push more than the h.264. For me the new Black Magic Pocket Camera is very interesting because it appears with will have a nice wide dynamic range and it shoots raw or to a editing friendly codec like ProRes so can perhaps push the image even farther because of it’s actually larger dynamic range.

Focus was extremely fast when used in combination with the Canon EOS 1D-X, with AF tracking enabled to keep track of the high speed planes at the airfield.

New Canon EOS 70D Lab and Real World Sample Pictures (dpreview)

dpreview updated their in-depth preview of the Canon EOS 70D with lab and real world sample pics (using a pre-production model). About the innovative Dual Pixel CMOS AF dpreview writes:

We’ve only had limited time with the 70D, though, which means it’s too early for us to say definitively how well its live view AF system works in practice. But based on what we’ve seen so far we’re pretty optimistic – it’s certainly streets ahead of anything Canon users have experienced so far.

Canon EOS 70D Auto-Focus Tests (Viewfinder & Live View with various lenses)

YouTube user Daero Lee posted a series of videos that show how the Canon EOS 70D‘s auto-focus works (and performs). Most videos tackle the Dual Pixel CMOS AF, but there are also some that show a view through the viewfinder, and how the AF performs. More videos after the break.
