Zusammenfassung: | Disclosed is an optical system comprising: a first lens group adjacent to an object side and having a first optical axis; a second lens group adjacent to an image side and having a second optical axis; and a first optical path conversion member disposed between the first lens group and the second lens group, wherein the second lens group can move. The optical system is in a wide state when the center of the second lens group overlaps with the first optical path conversion member in the second optical axis direction, and the optical system is in a tele-state when the center of the second lens group does not overlap with the first optical path conversion member in the second optical axis direction.
Est divulgué un système optique comprenant : un premier groupe de lentilles adjacent à un côté objet et ayant un premier axe optique ; un second groupe de lentilles adjacent à un côté image et ayant un second axe optique ; et un premier élément de conversion de trajet optique disposé entre le premier groupe de lentilles et le second groupe de lentilles, le second groupe de lentilles pouvant se déplacer. Le système optique est dans un état large lorsque le centre du second groupe de lentilles chevauche le premier élément de conversion de trajet optique dans la seconde direction d'axe optique, et le système optique est dans un état télé lorsque le centre du second groupe de lentilles ne chevauche pas le premier élément de conversion de trajet optique dans la seconde direction d'axe optique.
