Which one would you buy? my considerations for each lens is:


Canon ef-s 17-55 f2.8 << for me it's perfect. BUT, price is a bit steep


tamron 17-50 f.28 VC << truth be told, I don't know a thing about tamron lenses... so give me a proper review as I don't find the one in here is quite helpful... Sorry bryan I need a personal field experience and comparison with the canon 17-55


canon ef-s 15-85 f3.5-5.6 << love the zoom range. But, I probably want a bigger aperture...


So... please help... and if there are other lenses that you have in mind, spill the beans!


Thanks
