I don't understand why you don't understand this. I switched to nikon last year, but I still have my 7d. It's about to be sold, but would get a new lease of life as a raw shooter. I'm not about to invest in canon gear again, especially as I have no ff canon lenses. Anyhoo, I've seen magic lantern getting certain things to work on the 7d. From what I've seen of this hack there is little actual processing that's going on. And 7d is newer generation than 50d, so I may just hold my breath a little :)
