Patent ID: 7872806

Claim:
An electronic image pickup apparatus, comprising: an optical path-bending zoom optical system and an electronic image pickup device, wherein: said optical path-bending zoom optical system comprises a 1-1 st lens group having negative refracting power and said 1-1 st lens group having negative refracting power comprising a reflecting optical element for bending an optical path, a 1-2 nd lens group comprising a positive lens and a second lens group having positive refracting power, said second lens group moves only toward an object side of said optical path-bending zoom optical system for zooming from a wide-angle end to a telephoto end of said optical path-bending zoom optical system, the electronic image pickup device is disposed on an image side of said optical path-bending zoom optical system, a total number of reflecting optical elements for bending said optical path in said optical path-bending zoom optical system is one, said reflecting optical element has fixed shape, and during both zooming and focusing, all lens groups including said 1-2 nd lens group and located between said 1-2 nd lens group and the object side are fixed.
