Canon EOS 5D Mark III vs Blackmagic Design Cinema Camera

From OneRiver Media
The folks at OneRiver Media decided to compare the EF model of the Blackmagic Design Cinema Camera with the Canon EOS 5D Mark III. They put both cameras through a battery of tests to compare sharpness, dynamic range, lowlight performance as well as a few others.
OneRiver recommends that you download the video to your computer, as they weren’t completely happy with the compression on Vimeo. Although, even the compressed file shows the differences in the two cameras pretty easily.
After several DAYS of trying to upload this video to Vimeo, we’ve ultimately had to reduce the bit-rate compression down to 18mbps (Vimeo recommends 5mbps, ha!), which is down from our minimum quality level of 40mbps. This means the SOURCE file you can download will also inhibit some amount of compression blocking and smearing, even in the Cinema Camera footage, which doesn’t originally exist in our ProRes master file. We’ve tried EVERYTHING, multiple types of uploads, different encoding methods, you name it. This is as best as it will get unless someone can host our 40mbps H.264 file (about 3GB) on their server that the world can download from.
Although the downloadable source file is a little better than the streaming version, it still doesn’t compare to the original ProRes source file which imposes no banding, compression artifacts, or chrominance sub-sampling (down from 4:4:4 to H.264′s 4:2:0 space). Please keep this in mind when viewing.
Unfortunately Vimeo only allows 100 downloads per day, so check back to download the 2GB file if the queue is filled. And remember to always watch in FULL 1080 HD or you will have added scaling and moiré issues on some of the tests than what is already been added by Vimeo and our horrid bit-rate restrictions.
Background: This video compares the Blackmagic Design Cinema Camera and the Canon 5D Mark III in several tests. This includes dynamic range, sharpness, pushing levels, banding, artifacts, rolling shutter, chromakeying, wide/telephoto lengths, DOF (depth of field), low light, macro blocking, contrast, and more.
Thanks for watching. Hope this is as informative for you as it was for me making it.
