Depends on your definition of "street photography."

You say you favor spontaneity. If you want to do handheld fast-paced zone-focused work, then you'd need to hit something like 1/250 @ f/16 or higher with that 80mm lens -- so if most city sidewalks are shaded, figure that even ISO 400 will only give you 1/250 @ f/8, SO..... fuggedaboutit!
