I have a new Canon XSi and am need of some good focusing techniques. So far - in the six days I've owned it - I'm not particularly pleased with the 9-point autofocus. I've played with using the center autofocus point, focusing on my subject, then recomposing and that seems to work okay. I've played with manually focusing also, and that's ok too. Primarily I've been in Tv or Av mode due to dim lighting/indoor shots.
But what do you use?!
What methods or tricks are there if, for example, I'm taking a portrait of someone and I want her eyes nice and sharp? Is auto or manual focus better?
And if there's two people in the picture, how can I be sure to get both of their eyes sharply focused?
Also, is there a way to "zoom" in to your focal point w/o actually zooming? That probably makes no sense, but I thought I read in my manual somewhere that you could zoom in to focus and then recompose your shot before taking it...how does that work?!
Sorry to sound like a dufus
but would appreciate any and all input. I do have my manual and plan to look it over again tonite, but figured it would also be to my advantage to have it explained by those who actually do it.
Thanks so much!!
