Deciding which lens to use is one of the most important factors for street photography. You may be tempted to use a telephoto lens, but that’s more than likely to result in more harm than good. You don’t want to be that creepy person standing across the road aiming a giant lens at strangers. If you want to look inconspicuous you’re going to need to get up close and among the action. Use a wide-angle lens and get lost in a busy crowd. Many street photographers choose a compact camera that’s less confronting than a large DSLR, the advantages being smaller, lightweight, and discreet.
