摘要： In an expensive zoom lens that has a zoom ratio of as high as about 5 and high optical performance and is very thin in its depth direction, the optical path of the optical system is easily bendable by reflecting optical members. The zoom lens includes a plurality of lens groups G1 to G5, and has a lens group F (G1) located nearest to the object side thereof. The first optical path bending is carried out by the first reflecting optical member PR located in the lens group F, and the second optical path bending is carried out by the second reflecting optical member RM located on an image side of the zoom lens with respect to the lens group F in a direction different from the first optical path bending direction. The lens group F remains substantially fixed with respect to an image plane I during zooming.

摘要： The invention relates to a zoom lens favorable for offering a tradeoff between slimming down a lens system upon received in an associated lens mount and making sure a small F-number. There is a zoom lens provided, which comprises, in order from its object side, a first lens group G1 having negative refracting power, a second lens group G2 having positive refracting power, and a third lens group G3 having positive refracting power. Upon zooming from a wide-angle end to a telephoto end, the first second and third lens groups G1, G2 and G3 each move along an optical axis while a spacing between the first lens group and the second lens group becomes narrow and a spacing between the second lens group and the third lens group becomes wide. The first lens group G1 comprises one single lens that is a double-concave negative lens or two lenses: a double-concave negative lens and a positive lens. The second lens group G2 comprises two positive lenses and one negative lens. At least one of the positive lenses has an aspheric lens surface. The zoom lens satisfies condition (1) that defines the relation between the total length of the lens system and the height of a marginal ray at the entrance surface in the first lens group G1.
