    摘要: An internal focus lens comprising sequentially from an object side a first lens group having a positive refractive power; a second lens group having a negative refractive power; and a third lens group having a positive refractive power. The second lens group is configured by a simple lens element and is moved along an optical axis to perform focusing. The internal focus lens satisfies condition expressions (1) 0.48

    摘要: An internal focus lens includes sequentially from an object side, a first lens group having a positive refractive power; a second lens group having a negative refractive power; and a third lens group having a positive refractive power. The first lens group includes an anti-vibration lens formed by a negative lens that is moved in an orthogonal direction with respect to an optical axis to correct image blur consequent to optical system vibration, and further includes an aperture stop disposed farther on an image side of the first lens group than the anti-vibration lens. The second lens group is moved along the optical axis to perform focusing.

    摘要: A zoom lens includes a first lens group including at least one positive lens and having a positive refractive power as a whole, a second lens group having a negative refractive power, a third lens group having a positive refractive power, and a fourth lens group having a positive refractive power wherein the first to the fourth lens groups are arranged sequentially from a subject. When magnification is varied from a wide angle end to a telephoto end, the second lens group is moved along an optical axis from the subject-side to an image plane. When given conditions are fulfilled, a small zoom lens with less manufacturing costs, high optical performance, and high magnification is realized.
