    Abstract: An optical imaging system includes a first lens having an object-side surface that is convex; a second lens having a refractive power and a refractive index of 1.65 or more; a third lens having a refractive power; a fourth lens having a refractive power and an object-side surface that is convex; a fifth lens having a refractive power; a sixth lens having a positive refractive power; and a seventh lens having an object-side surface that is convex, wherein the first lens through the seventh lens are sequentially disposed in numerical order from an object side of the optical imaging system toward an imaging plane of the optical imaging system, and two or more of the first lens and the third lens through the seventh lens have a refractive index of 1.6 or more.

    Abstract: An optical imaging system includes a first lens group having negative refractive power, a second lens group having positive refractive power, and a third lens group having negative refractive power, wherein the second lens group and the third lens group are configured to move in an optical axis direction to adjust a focal length and magnification, and the following conditional expression is satisfied,


    FNOt≤3.6,



    where FNOt is an F value at a telephoto end of the optical imaging system.

    Abstract: An optical imaging system includes a first lens, a second lens, a third lens, a fourth lens, a fifth lens, a sixth lens, and a seventh lens sequentially arranged along an optical axis from an object side toward an image side. The fifth lens has a positive refractive power, a focal length of the fifth lens is smaller than an overall focal length of the optical imaging system, and −0.38≤R10/f≤−0.32, where R10 is a radius of curvature of an image-side surface of the fifth lens and f is the overall focal length of the optical imaging system.
