Hello again, i would just like to inform everyone of the Magic Lantern Firmware. I have installed it on my Canon 550D and it has helped me improve my filming because it adds new features that turn you $600 camera into a $6000 camera.
Here is a short video explaining what the firmware does:
The only problem with this firmware is that it voids your warranty and at the moment only supports a few cameras. That being said new features are being added all the time to add to you film making arsenal.
