This lens is a good lens has good features such as IS/F2.8/Fast Focus/17 mm wide is good enough for alot of situations.

But the killer for me is that F#@%ing CHROMATIC ABORATION ..jesus christ I wish this lens wasn't so bad with it !!

I also have a $300 TOKINA 19-35mm f/3.5-4.5 that I wanted this lens to replace.My TOKINA creates almost no chromatic aberation, by almost I mean it creates at least 90 percent less Chromatic ABORATION then the canon 17-55 at over $1,000 why ?

I have no other lens in my bag that produce that much Chromatic A. I'ved had those other lens for over 5 years, so I was used to not having to deal with them...but now finding workarounds to remove those CA is impacting my worflow and speed way too much.

I will mostlikly return or call canon on monday and ask if they could fix that problem if not... I'm getting my money back to get something else.

So other then that the Chromatic Aberation and oh..also flares like hell..this lens would be perfect!!
And about this dust issue ..Not a problem for me at all.Eevn if this lens had no CA problem..the Dust problem would not be a problem for me.
