To actually contribute to this thread, I view street photography as walking down the street, downtown area, and taking photos of whatever. For this I typically use a 50 prime, most often my 50 f/1.4. If I went to shoot something far away and get a compressed look, I take my 135L. That's as long as I'll go for this type of photography simply for convenience. I take the grip OFF my 5D3 and use that, because I hate walking around public with 1D bodies when I'm not really shooting anything that would require a 1D body. I want to find an HDR image I did downtown back in June at night, so I will look for it.
