I need to look more into that then. I saw footage of the menus in the alpha version and thought the menus didn't look too user friendly. Plus, I'm reluctant to put anything on this camera if it's still in alpha or beta. That usually means SOMEthing isn't working right.
I thought there was already a stable release for the 7D...guess not yet. I have used ML to all my canon cameras and never had a problem. Right now Im using ''Nightly Builts'' on my 60D for shooting RAW video and everything works normally.
Of course it comes with a risk...!
