i shoot tethered 98% of times. I only use the leaf in Situations where i am in 100% control and then there is always a computer closeby. otherwise the canon comes out...
the problem i have is that when i try to change the setting on the back with a battery installed, i can choose the camera model, but i can't confirm it. I can hit the 'accept' button as much as i like, nothing happens. i can't get into the top level. the only way to get there is to press the thumb wheel, but then the setting isn't stored.
