I use Final Cut Pro with my 7D, but I do transcode all of my footage to ProRes before editing. It works great! Compressor is an excellent tool for transcoding the 7D footage, allowing me to slow my 60p footage to 24p.
I actually downloaded a trial version of Vegas on a Dell laptop this weekend, and I really like the interface, but I felt handcuffed, mostly because I don’t understand what tools are available to me. I imported the H.264 files from the 7D, and tried to edit, but I couldn’t get real-time playback. I’m sure my hardware was not up to snuff for that footage. It was pretty much impossible to edit under those conditions. I probably should have used Vegas to convert the files to something less resource intensive. Maybe I’ll try that and see what happens. Unfortunately, I haven’t found a good solution for editing 7D files natively.
