"WebFor non-zoom lenses, internal focusing probably means that the bellows effect (in which air is sucked into the lens) is minimised since the outside of the lens probably won't move during focusing. That means the interior of your camera doesn't get humid or dusty (and so less crud adheres to the sensor). " - In an internal focusing telescope
