iv been running magic lantern for close to a year now on and off iv got it installed a sd card only for ml shots and i will say i love it the bracketing function for hdr has all changed, it now takes as meany shots as it needs to get all the exposure it needs and automatically you just press the shoot button once and it fires away usually 3 to 6 shots for me but it can do lot more
and chris the only firmware you need to update to is the genuine canon 60D 1.1.1 , ml dont realy update the firmware just changes it while the card is in the cam with Ml installed to it, when you turn the cam off and take that card out it reverts back to the 1.1.1 firmware instantly
