Abstract
To obtain a high imaging performance even for a relatively long focal length in a zoom lens provided with an optical-path bending member for bending an optical path. The following are included: a first group of lenses Ghaving a positive refracting power, a second group of lenses Ghaving a negative refracting power, a third group of lenses Ghaving a positive refracting power, and a fourth group of lenses Ghaving a positive refracting power arranged in that order from the object side to the image surface side. Zooming is performed by moving the second group of lenses Gand fourth group of lenses Galong an optical axis. The first group of lenses Gis constituted of a group of positive lenses Lhaving a positive refracting power and an optical-path bending member Lfor bending an optical path arranged in that order from the object side to the image face side.
