As already pointed out, the distortion visible in your shot does not depend on the lens at all: it's perspective.
If you crouched a bit ad kept the sensor plane parallel to the fence, you'd get no distortion.
Or - from the standpoint you shot from - by using a tilt-shift lens, but that's another story and not really convenient for fast-paced sreet photography.
And anyway you'd need to understand perspective first, which you don't really seem to be keen on.
Ah... it's not a good habit to ask questions when you don't consider answers.
Especially if they are 100% consistent with each other
