Abstract
The present disclosure discloses a camera apparatus including a first optical system and a second optical system. The second optical system includes a secondary reflecting mirror, a main reflecting mirror with an opening in a center area thereof, and a lens group, which are sequentially arranged from an object side to an image side. Light from the object side is sequentially reflected by the main reflecting mirror and the secondary reflecting mirror, and then enters the lens group through the opening. A total effective focal length F1 of the first optical system and a total effective focal length F2 of the second optical system satisfy: F2/F1>10.
