I don't understand this thread at all....are you sure we are all street photogs here.

You use everything and the close up mfd of wides is ...????

28 or 35mm are regarded as the classic or golden age FLs and away from these wider or longer is up to the photographer and the requirements of the scene.
Street comprises; portraits in environment or isolated, buildings and architecture, groups or individuals, human or animal ...vegetable or mineral.

Are we catching on?

I shoot in 21, 28, 35, 50 & 100 but could easily incorporate wider and longer
I'm not the biggest fan of 50mm but for some shots I couldn't have done without it. My fav is 21mm...its so general purpose

I set myself a limit of 100mm but the decision had nothing to do with the subjects or scenes
