I have a 40D, Sigma 30, and Nifty 50 (Mk i), and I'm going abroad after the new year for a few months.
I'm debating whether to invest in a wide angle (Tokina 11-16 2.8, Sigma 10-20, etc.) or to get the new S100 for wide angle shots since it can shoot RAW. It'd also be handy to have the video capability too, but I'm not sure how much I'd use it.
I've tested a Sigma 10-20 on my 40D and it didn't impress me at all. I liked the wideness, but the sharpness, colors, etc. were a bit bland imo after I put em' up on LR.
I've heard the Tokina is a really good wide for APS-C sensor bodies but I haven't tried it yet, but of course it's still around $600+.
I'm thinking it would be better to have two cameras on me while moving around since lens changing might cause me to miss an opportunity but my overall goal is for sharp image quality.
What do you guys think? In your experience (maybe with an S95), can image quality compare to using a wide angle on a cropped body?
