It rocks hard, and is safe to use.
I even used it on last event I covered, with absurd settings of 100/3200 at f/1.4, developed with --soft-film=4 and I'm more than pleased with effects.
Check it out!I took about 1100 frames, all with dual ISO. Processed them with Barracuda GUI (took whole night to process on Q6600

). Zero problem whatsoever.
Magic Lantern together with dual ISO module are the real 2.0 7D firmware update, not the Canon one
