Your right there the best street photographers only use 28mm
Indeed, actually a VERY good example of why is this shot :-
Taken with a Yashicamat LM ( with 80mm lens but that's MF so I think that's about 50mm equiv). Being MF I could easilly crop it BUT there is no way I could have taken the shot with a zoom. There was a building in the way. I'll be honest and self critique my photo and say it would have been better closer and me being slightly to the right. Guess what? right = closer to the subject.
