To all candid street photography shooters: This is a major deficiency of mine - namely I think because I would like to be as discreet as possible, and sometimes that's not possible due to the kind of equipment you have. I'm curious what techniques people use, and especially, what focal lengths work best for them. I already feel like I have the ideal lens for this, which is the Tokina 50-135 f2.8. Unfortunately, in casual use, it's like attaching a brick to the front of your camera. So I am thinking about getting a prime for something like this. I would use a D90 for this, so I am thinking that a 50mm, 60mm, 85mm, or 105mm FL would work best for it, but I'm just trying to keep as small a rig as possible. I'm also not interested in accumulating any more DX glass. I'd be okay with MF as well. Any tips? PS: I really liked MSUSpartan's NYC shots, but 1. I am not ready to invest $9000 in a Leica M system and 2. some people here scared him off!
