I know that the Canon Kiss X4 is just another name for the T2i / 550D camera but just wanted to be sure that Magic Lantern works fine with it. Wouldn't want to screw up a perfectly new camera! Can anyone confirm?

I ve seen a couple of references that it does, but can't confirm specifically. What is your official firmware version ? 1.09 is what current Magic Lantern is running off of.

I can confirm it works perfectly on my Kiss x4. The 550d / t2i / kiss x4 firmware is all the same too.

Thanks Warren! I'll go ahead with the installation then! Wish me luck!
