ok,99% of all my pics are taken at nite in either a niteclub scene or music/bar venue and take action/unsuspecting pics of people dancing/whatever. I need a camera that responds fast to the shutter button.meaning i need it to take the picture the instant i press the button. I had a canon s30 and it worked great,it was stolen,so i bought a canon a75 and its ok,but seems to lag trying to focus. Also I sometimes,well actually quite a bit "blind" shoot so, the af-assist beam is my focal point. Ive basically just used the "auto" setting, since I have experimented with the built in scene modes with no luck. a friend just bought a canon rebel slr, it takes great action shots in daylight and hes sceptical to let me "borrow" it one night,which,i dont blame him. so i come here looking for advise. i am partial to canon products, but am open minded to other brands. thanks in advance for any input.
