Abstract

Et autofokussystem (10) innbefattende en brakett (18) for å fastholde en linse (14). Braketten (18) har et lager (22) festet til seg eller Integrert med denne. Lageret (22) er eksentrisk i forhold til linsen (14) og er virksomt til å bevege linsen (14) langs sin optiske akse (16). Bevegelsen skjer ved hjelp av en driv- mekanlsme (34) på en Jevn måte og uten smøremiddel. I en bestemt utførelse er lageret (22) eksentrisk og utvendig av et sylindrisk volum avgrenset av linsens (14) omkrets .
