Well, I took the bait and purchased this lens a number of months ago. However being amateur at photography, I'm getting the feeling that I've been making a number of mistakes with this lens. I'm the sort of person that doesn't mind learning from my own mistakes, but prefer to learn from others if I have the opportunity, so hence this thread.
I got a bit over excited with the large aperture and the bokeh. As such, I've taken a number of photo's (most) at f2.8 that have ended up been soft, or slightly out of focus. Trying to photograph my 2 y.o. daughter who never stops isn't easy. Having it on my 550D which doesn't have the fastest AF probably doesn't help either I'm guessing.
So I was wondering - does anyone have any hints / suggestions to get the most out of this lens - especially when it comes to portrait / people style photography?
I'm thinking from what I've observed so far that I should be shooting more at f4, or maybe f5.6 for sharpness in most situations, and only use f2.8 if the subject is either some distance away, and/or I'm only shooting one subject that is still so I have time to get the focus right. Does this sound about right, or does anyone have any other tips for getting the most out of this lens (or just using it correctly in the first place)
