Magic Lantern: the hack that helped sell so many Canon 5D Mk III cameras to videographers, is supposedly being blocked in the company’s latest firmware. According to the Magic Lantern forums, the company blocks the initialization of Magic Lantern in firmware 1.3.3–which is very odd because according to the original poster, they can’t find any info on it. Nor can we, and nor can Canon Rumors.
Planet5D states that this isn’t the first occurrence of Canon blocking Magic Lantern. The team had to make adjustments for firmware 1.2.3 when it hit.
Deeper into the forum thread, users start to recommend that the person downgrade their firmware using EOS Utility. The users state that this works, though there is also stipulation and mentioning that Canon may block downgrading.
Magic Lantern is incredibly important to videographers because the team discovered a RAW CineDNG video output on the camera around a year ago. Then they found a way to record it, improved it, and then found a way to get it to 14 stops of dynamic range. But shortly after that, they pushed it to 15 stops. Shooting in RAW gives a cinema team a lot more versatility to create better video in the post-production phase on a budget. The only other way to do it would be to go for Black Magic cameras or snag something from the Cinema EOS line–but that is out of reach for many cinematographers.
