More Blackmagic 4k videos/tests and review will be at mediahalo.com/articles/bmc4k/?vim
Not overly scientific or whatnot, just a realworldish test. tried to keep it consistant but keep in mind no camera here has exactly the same sensor size. didn't attempt to get perfect exposure, just in the ballpark, this is just a test for Moire/Aliasing.
The takwaway is that the BMC4k is great, very great. They're all great actually except for the 5d2(great for other reasons). but putting that one aside since it's by far the oldest and least refined for video, the rx10 displays the most artifacting, but don't think for a second that it's a failure, because it's far from it. It may not control artifcating as well as the C100 or BMC4k, but it actually is quite good. that little strainer on the owl is a nightmare for any camera.
Aside from the details in the opening title, this was lit with a 2x55watt kino-flowish type fixture, daylight balanced.
Main thing to keep in mind is that the bmc is the only 4k camera here, so it's being downscaled to match the others.
