I had that 23 for a while on my camera and truly it was fabulous. But I'm just starting the street photo adventure, and the fact is that 23 is more universal for street and any other occasion. But you have to be really close to your subject and it is stressful for me. xD But maybe it is a good oportunity to overcome that fear and that's why I considering this lens. But i just wonted to know how good is the 35 because of its price which is slightly lower than 23.
