Hello Gurus,
Seeking for reviews about the lens Canon EF-S 17-55 f/2.8 IS USM, I found this forum and it´s awesome, but I would like to hear your opinion about this canon lens, because I have two lens in my target, first i can buy a Canon EF-S 17-55 f/2.8 IS USM, fast focus, great colors and cheap, and the second option Canon EF 16-35mm f/2.8L II USM, fast focus, great colors, sharper, super wide and is a L lens, but is more expensive.
For the Canon EF-S 17-55 f/2.8 IS USM, i have some concern about the dust speck, but some collegues tell me that it´s not a problem with the new version of this lens.
So gurus, What the best choice? 
Regards,
Rodrigo Paixao.
