I think you could go as far as saying, because the lens is telephoto, its just not street, so that tog doesn't exist.
50mm is a starter length, no longer than that, its definitely borderline on a crop sensor, but I guess if you can shoot street @ 50, its only a short hop to 20.
Gilden is a nutter, I think he has it a little warped, like the general public owes him a living or something, but I guess its the same mentality as the paparazzi except the peeps they shoot make their living from exposure, unlike average joe who just wants to get to work without some toilet blocking his way and blinding him with flash, walking away like nothing happened.....no interaction, no subtleties, no blending in, a nod and a wink..nothing, its almost assault.
