it spins me out that people r still worried about magic lantern, IMHO it is the essential t2i accessory.
seriously bro, don't even think about it, just do it!
for like half an hours' effort it will turn ur camera into a weapon.
forget ur handycam, once u get used to shooting video on ur t2i with ML I'd be surprised if u ever use it again! lol
it is only a slight addition to ur workflow, but the rewards just keep coming.
don't shoot video? no probs.
try the intervalometer, bulb timer,
Christ, just the Kelvin temps and intermediate iso r worth it alone.
do it bro, u won't regret it.
