@Lomo: i'm down with the sickness right now, so i'm not sure if i'll be out this weekend street shooting. maybe next time, bro.
@adrian: the wide angle focal length is perfect for street photography, especially for capturing street scenes. The only problem is i think the 17-50mm f2.8 is a little big, so it would be pretty obvious in the streets. I personally prefer using prime lenses for it's compact size and no zoom required. This way, it forces me to anticipate the composition of the scene before i put my eyes on the viewfinder.
