Fokussieren erfolgt in der Regel durch Änderung des Abstandes der (Front)Linsen zum Sensor/Film. Dabei muss je nach Objektiv eine hohe Masse bewegt werdenm was unter anderem von der Brennweite, der Lichtstärke oder der Naheinstellgrenze abhängt. Objektive mit Innenfokussierung haben eine Linsengruppe, die innerhalb des Objektives verschoben werden, was die Masse drastisch reduziert und den Motor schont.

Durch diese Methode wird allerdings nicht nur fokussiert sondern als "Fehler" auch die Brennweite leicht verändert. Dafür kann aber meist auch die Naheinstellgrenze kürzer gehalten werden, was Makrofotografen entgegen kommt.

Eine Verbesserung der Innenfokussierung stellt der Einsatz von Floating elements dar.

Was immer gerne von den Händlern verschwiegen wird wie sich die Staubelastung bei Innenfokussierung darstellt. Bei ausfahrbarem Tubus ensteht ein sogenannter Staubsaugereffekt. Das bedeutet,daß Staub aus der Umgbebungsluft in das Objektiv/Kamera gezogen wird. Es muss damit gerechnet werden,daß mit hohem finaziellen Aufwand eine Reinigung des Objektives bzw. der Kamera vorgenommen werden muss.Bei innenfokussierung ist das Objektiv davon nicht sehr betroffen.
