  • Fixed focal length lens system and camera
    Patent number: 11467374
    Abstract: A fixed focal length lens system includes, in order from an object side to an image side, first lens element having negative power, second lens element having negative power, third lens element having positive power, fourth lens element having power, fifth lens element having power, and sixth lens element having positive power. The third lens element is a positive meniscus lens element having a convex surface on the image side. At least one of second to sixth lens elements is made of glass. The fixed focal length lens system satisfies condition (1) below: 0<(L1R2+L2R1)/(L1R2?L2R1)<100??(1) where L1R2 is a radius of curvature of an image-side surface of first lens element, and L2R1 is a radius of curvature of an object-side surface of second lens element.
