Magic Lantern is an open platform for developing enhancements to the Canon 5D Mark II full frame digital SLR, a camera that offers:
the use of a wide range of lenses (anything that can be adapted to the EF mount) a 35mm full-frame sensor the size of VistaVision. This means shallower native depth-of-field than anything on the market, except for the Phantom 65. a dynamic range and latitude close to the capabilities of high-end HD cameras. The low-light performance.
Magic Lantern has written extensions and widgets that address firmware issues in working with the 5D Mark II on a film or video set.
The first set of fixes target audio limitations of the camera, but there are some video enhancements included, too:
On-screen audio meters Manual gain control with no AGC Zebra stripes (video peaking) Custom Cropmarks for 16:9, 2.35:1, 4:3 and any other format Control of focus and bracketing
