Red One, Canon 5D Mk II, and Panasonic Lumix GH1 Footage Comparison from Birns and Sawyer on Vimeo.
I suppose one lesson of this short clip—comparing footage from the Red One, Canon 5D Mark II, and Panasonic Lumix GH1 with a range of lenses—is that a woman in a black dress makes for great test video.
Oh, and I'm admittedly surprised by how well the GH1 appears to keep up with the Red One and 5D Mark II. Of course, at full resolution, it might be a different story. But if you were really torn between the Red One and GH1 for some reason, I guess your decision got a bit harder.
