What focal length do you people prefer for general travel/street/walk around lenses? I'm trying to narrow down what lenses I need since I just made the switch to Sony and I'm a poorfag who's only used 3 lenses, the 18-55 kit lens on Nikon and Sony cameras and the Nikkor 35mm prime, neither of which are particularly good quality compared to what's out there.

Something like the Sigma E mount 18-35 f/1.8 looks like a perfect street photography lens because it gives you the framing and depth of field that a 35mm has but still allows you to drop down to 18 in tight spots, but what do you people prefer?
