UPDATE: here’s 2.5K raw in 1:1 crop mode –
Huge thanks go to A1ex, g3gg0, 1% and the whole Magic Lantern team.
I have no other words to describe it – this is huge news.
Magic Lantern have done the seemingly impossible and given us a continuous raw recording mode on the Canon 5D Mark III. Once activated in the menus the 5D Mark III becomes essentially a full frame Blackmagic Cinema Camera and amazingly mine has not yet exploded. No more short bursts of raw, this is the real thing.
