Another 2-ish questions 1/ When people say "focus on the eyes" am I supposed to: (a) use manual focus? Or do I (b) 'manually' choose an AF point and then point the chosen point at the eyes? 1.5/ What is manual focus for? (maybe I should be asking how do I use it?!! haha) Or am I missing the point? Becuase the eye hole isn't big enough for me to see if things are in focus!! I can generally make out what is "sort of" in focus, but I'm pretty sure my eyes through the eyehole can't match the AF mechanism - and I don't mean in terms of speed. 2/ When will I get a desire to buy an external flash? (might seem weird, but it's a serious question. I mean, I would want to buy a 500mm lens when I get into nature photography or something - haha, but I don't really get when I would want a flash unit.) Thanks very much! Have a nice day!
