The T2i can not fire studio strobe lighting in live view mode. the issue is that other cams like 7d, 40D , 5d etc allow to disable (enable?)
silent mode and also disable exposure simulation (not sure if that is required or not) but T2i does not allow. What I would love to see is the ability to enable live view, see well enough to use magic lantern to manual focus and then fire off a still shot using studio strobe units.
What do you think?
thnx
