摘要： PROBLEM TO BE SOLVED: To provide an inner focus type lens that is small and has a high imaging performance, the lens having a vibration-proof lens light in weight and less in an amount of movement for image blur correction.SOLUTION: This inner focus type lens comprises, in order from the object side, a first lens group Gof positive refractive power, a second lens group Gof negative refractive power, and a third lens group Gof positive refractive power. The first lens group Gcomprises a negative lens Lhaving the function of a vibration-proof lens, and an aperture stop STP. By including the vibration-proof lens in the first lens group G, the imaging magnification of the vibration-proof lens itself can be increased. Accordingly, an amount of movement of the vibration-proof lens during vibration-proof correction can be decreased. Since the vibration-proof lens is composed of a single negative lens L, the weight of the movable lens can be made light.
