Thanks guys!
@musket - I'm really having fun experimenting with the ST-E2 and my 430EX/420EX. For this shot they were both placed in front of my daughter (one a little to the left and one a little to the right) and bounced off the ceiling... I was sitting off to the side... I've been incredible pleased with the results...
@Paul - Yeah, for my daughter i did need to get fairly close... so the 85mm 1.8 is just got bumped up to the top of my "wish list". LOL! I'm a lazy guy at heart so 99.9% of the time i reach for one of my zoom lenses... but this shot convinced me I need to start relying less on zooms...
oh... and i know about reluctant subjects! LOL!
