I am planning on doing some street photography work to help out the Bachelor of Social Work Student Association that I am a part of and was wondering what lenses the street photographers on this forum would recommend. I am shooting with a 40D, and am on a pretty limited budget since I will be a student for the next couple of years. I currently only have the 28-135mm and the 50mm f/1.8. I would like to get something at the wide end to compliment the 28-135, and was thinking about picking up a Tokina 12-24 for wide shots. I also am considering the 17-55 f/2.8 IS, but it is double the price and not as wide. Would I be better off going for more on the wide end, or more on the long end? What lens do you prefer for general shooting?
