摘要：A taking lens apparatus includes a zoom lens system that is composed of aplurality of lens units and that achieves zooming by varying the distances between thelens units and an image sensor that converts the optical image formed by the zoom lens

system into an electrical signal. The zoom lens system has, from the object side,: a firstlens unit having a negative optical power, a second lens unit disposed on the image sideof the first lens unit and having a negative optical power, a third lens unit disposed on theimage side of the second lens unit and having a positive optical power, a fourth lens unitdisposed on the image side of the third lens unit and having a positive optical power, anda fifth lens unit disposed on the image side of the fourth lens unit and having a positiveoptical power. During zooming, the first lens unit remains stationary relative to the imagesensor, and the second and third lens units move.
