Abstract: A zoom lens consists of a first lens group having positive refractive power, a second lens group having negative refractive power, a third lens group having positive refractive power, a fourth lens group having positive refractive power, and a fifth lens group having positive refractive power in this order from an object side. The third lens group consists of a 3-1st lens group having positive refractive power and a 3-2nd lens group having negative refractive power in this order from the object side. A hand shake blur is corrected by moving the 3-2nd lens group in a direction perpendicular to optical axis. Magnification is changed by changing distances between the lens groups while the fifth lens group is fixed.

Abstract: An objective lens for endoscopes is constituted essentially by, in order from the object side: a negative first lens having a concave surface toward the image side; a first cemented lens, formed by cementing a second lens and a third lens having refractive powers with signs opposite each other, provided in this order from the object side, together; a stop; a positive fourth lens having a convex surface toward the image side; and a second cemented lens, formed by cementing a positive fifth lens and a negative sixth lens, provided in this order from the object side, together, in which the coupling surface is convex toward the image side. Focusing from an object at a most distant point to an object at a most proximal point is performed by moving only the second cemented lens. A predetermined conditional formula is satisfied.
