Alexander Fox of 5DFilmmaking.com offers a great video interview introducing both the author and the great features of the Magic Lantern Canon firmware add-on.
Trammel Hudson author of the Magic Lantern tells the story of how he came to develop this uniquely powerful firmware for the Canon 5D Mark II and other models and later shows some of the key audio and video features that he has been able to enable on Canon cameras.
Must watch. 9/10.
