(FR) SYSTÈME D'ÉQUILIBRAGE DE CENTRE DE GRAVITÉ DE ZOOM
Abstract: front page image
(EN)A lens system and methods for making and using same. The lens system can include a lens barrel (100). The lens barrel (100) can comprise one or more movable lens groups (120) and a cam barrel (160) being associated with the one or more movable lens groups (120). The cam barrel (160) can be configured to balance a center of gravity (128) of the one or more movable lens groups (120) and, thus, to balance the center of gravity (128) of the lens barrel (100).
(FR)L'invention concerne un système d'objectif et ses procédés de fabrication et d'utilisation. Le système d'objectif peut comprendre un barillet d'objectif (100). Le barillet d'objectif (100) peut comprendre un ou plusieurs groupes d'objectifs mobiles (120) et un barillet de came (160) associé auxdits un ou plusieurs groupes d'objectif mobiles (120). Le barillet de came (160) peut être configuré pour équilibrer un centre de gravité (128) desdits un ou plusieurs groupes d'objectifs mobiles (120) et, ainsi, pour équilibrer le centre de gravité (128) du barillet d'objectif (100).
