ISO is raised when there is not enough light to keep proper exposure but higher iso means more noise. I always use the lowest ISO setting possible when shooting.
it also has the 3.5m and the 8.5 m ... which is ????????
those options are for changing the lens min focusing distance on a 400mm lens you will find yourself shooting over 8.5m most times so by setting it there the lens is supposed to AF faster.
