I'm interested in getting serious with filmmaking and I'm planning on purchasing a DSLR to upgrade from an HD Camcorder. For the past month or so, I've been looking at the Canon T3i. It's not overly expensive and the tilting LCD is a big plus (coming from a camcorder user). The only thing that's making me hesitate is the new T4i which features autofocus. I've been using a camcorder for three years and it's all autofocus, so I've never had to use manual during filming.
Is manual focus when shooting videos that critical? Or should I pay the extra $200 and get the new T4i with auto video focus?
If it helps, I plan on doing a lot of different movies, some including action.
Any input is greatly appreciated.
