Abstract: An optical system is provided. The optical system includes a first lens group that has a positive refractive power, a second lens group that has a negative refractive power, a third lens group that has a negative refractive power, a fourth lens group that has a positive refractive power, and a fifth lens group that includes one or more lens groups, in sequence from an object, wherein the first lens group and the fifth lens group are fixed and the third lens group moves parallel to an optical axis to perform focusing when adjusting a magnification of the optical system.

Abstract: In a lens assembly structure comprising a plurality of lens assemblies, according to the present invention, at least one part of assemblies among the plurality of lens assemblies comprises: a first lens group having a positive refractive power or a negative refractive power; a second lens group having a positive refractive power; and a bending structure for bending an optical path of the first lens group such that the optical path corresponds to an optical axis direction of the second lens group, wherein the bending structure is disposed on the optical path of the first lens group and an optical path of the second lens group, optical axes of the first lens groups disposed in each of the at least one part of lens assemblies meet at one point, and optical axes of the second lens groups disposed in each of the at least one part of lens assemblies may form a triangle.
