hey guys, i got a EOS 400D January this year, and yea, after months of experimenting with it, I'm thinking of getting new lenses. It's a little frustrating not being able to get the shots that I wanted because the lens (17-55mm, bodykit lens) that I'm using now.
I'm trying out shots that involve mostly close ups, like events: eg: music showcase, mini fashion shows etc. So, here I am, asking for suggestions, maybe those who are experienced in shooting for events?
here are some samples of my shots (which I hope to improve on)
clickclickclickclickclickclickI was looking at some lenses. Canon EF 17-40mm f/4.0 L USM Lens, which cost a bomb.
Any suggestions for Tamron or Sigma lenses? Yeah, it may not be as good, but I'm looking towards experimenting and doing it for fun, so I'll go something lower in budget.
Thank you.

the question is... what do you feel is lacking with your current setup? can/did you use flash? was it a popup or external flash? if you don't use flash, what was your limitation? was it focal length? was your shutter speed not fast enough? did you miss the shot because of poor focusing performance? if focus was an issue, was it because it was not fast enough? or your focus missed? or is this entirely an issue of image sharpness, contrast, etc from the raw?
i know it's a lot of questions, but that should give me a better idea of what you're really looking for.
