Abstract: A rear conversion lens, which may include a plurality of lenses may be disposed at a side of master lenses facing an image side for varying a focal length, and may include: a first lens having a positive refractive power; a second lens having a biconcave shape; a third lens having a positive refractive power; a fourth lens having a positive refractive power; and a fifth lens having a negative refractive power. The first to fifth lenses may be sequentially arranged in a direction from an object side to the image side.

Abstract: A single focus lens and a photographing apparatus including the single focus lens are provided. The photographing apparatus includes a single focus lens comprising: a first lens group having a positive refractive power, the first lens group including a first negative lens and a second negative lens arranged in succession at a most object side of the first lens group; a second lens group having a negative refractive power; and a third lens group having a positive refractive power and including a positive lens and a negative lens. The first to third lens groups are sequentially arranged in a direction from an object side to an image side.

Abstract: An inner focusing telephoto lens system and a photographing apparatus including the inner focusing telephoto lens system includes a relatively larger diameter lens and a lightweight focus lens group. The inner focusing telephoto lens system includes a first lens group having a positive refractive power, a second lens group having a negative refractive power, and a third lens group having the positive refractive power. The first lens group, second lens group and the third lens group are arranged sequentially from an object side to an image side. The inner focusing telephoto lens system performs focusing by moving the second lens group along an optical axis.
