FPS control:
You can lower the frame rate down to 4 fps at a shutter speed of 1/4 seconds, which gives you extreme low-light capabilities.
Overcranking doesn’t really work; the 60D hardly gets 35fps in 1080p. On the other hand, 500D and 50D can now record at 24p!
HDR video:
For high-contrast scenes with not-so-fast moving subjects, you can get great shadow and highlight detail.
This feature is enabled on all cameras, but older models may have synchronization issues.
Magic Lantern is an enhancement atop of Canon’s firmware that frees your Canon DSLR, allowing you to use many useful features. Initially developed for filmmakers, it now has functionality for both photo and video enthusiasts, including manual audio, zebras, focus assist tools, bracketing, motion detection and much more. It is an open (GPL) framework for developing extensions to the official software. It does not replace the existing firmware, but instead runs along side of it. There is no need to “uninstall” it – simply format your card to reboot to the stock Canon firmware.
