The bent zoom lens is configured to include, arranged in order from an object side, a first lens group GR1 having a positive refractive power, a second lens group GR2 having a negative refractive power, a third lens group GR3 having a positive refractive power, a fourth lens group GR4 having a negative refractive power, and a fifth lens group GR5 having a positive refractive power. The first lens group GR1 includes a single piece of meniscus lens having a negative refractive power and having a convex surface directed toward an object side, a prism that bends an optical path, and a single piece of double-convex lens having a positive refractive power.
