I just want to say THANK YOU to nanomad and anyone who worked on this port. I shoot wedding videos and events for a living, and my T4i usually sits in my bag as my backup cam. The other day my A-cam got rained on and stopped working, and it was such a relief to have even the alpha of Magic Lantern on my T4i so I could use zebras, focus peaking and custom ISOs.
There were only a few glitches, such as when I flick the switch from video-mode directly to "off" I would sometimes get an error and the camera would freeze. However this is pretty darn stable for alpha software, and it stood up great for almost a whole day of filming.
I've been following the thread and thought I should just pop on and say good work and thanks for saving the day.
