ABSTRACT:
A catadioptric lens system capable of an automatic focusing operation without the necessity of increasing the outer diameter of a lens barrel is provided. The catadioptric lens system comprises a focusing optical unit, a focusing optical unit holder capable of movement in a direction of an optical axis of the lens band for holding the focusing optical unit, and a driving means disposed between a mount and a reflecting mirror which is disposed to reflect light coming from an object toward an object side and connected directly or indirectly to the focusing optical unit holder for transmitting a driving force to the focusing optical unit holder at a reduced speed so as to move the focusing optical unit holder in the direction of the optical axis to effect focusing.
