Förkortningen betyder

IF = Internal Focusing

Förklaring från Nikon

Imagine being able to focus a lens without it changing in size. Nikon´s IF technology enables just that. All internal optical movement is limited to the interior of the nonextending lens barrel. This allows for a more compact, lightweight construction as well as a closer focusing distance. In addition, a smaller and lighter focusing lens group is employed to ensure faster focusing. The IF system is featured in most NIKKOR telephoto and selected NIKKOR zoom lenses.
