Philip Bloom posted this nice “real world” comparison between the Pansonic AF100, Sony F3, FS100 and the Canon 5D mark II. He covers usability, wide shots, moire, darkness, gain and more.
He wanted to stress that this isn’t the extremely precise (different lenses, outputs, color correction, etc.) but it’s still helpful to see the comparisons. The video claims to be part one in a series with the next being handling and features.

UPDATE: He just posted part two. Check it out below.
