Here's an amazing bit of footage posted by premiere Hollywood equipment rental house Birns and Sawyer on their Vimeo channel.
What's so amazing about it? It compares side-by-side-by side the output of three hype-worthy cameras - the 4k-capable digital cinema RED ONE camera (roughly $20k) and two DSLRs equipped with "movie" modes, the $3500 Canon 5D Mark II and the $2200 Panasonic Lumix GH1. This is the first time I've seen footage from the Panasonic, and the first time I have seen anyone cut together material from a RED with footage from a DSLR. What it shows is that the technology has definitely shifted and this new generation of DSLRs are game-changers in terms of comparing price to image quality.
