Title:
ZOOM LENS ASSEMBLY, IMAGE CAPTURE DEVICE, AND CAMERA
Document Type and Number:
WIPO Patent Application WO/2012/098617
Kind Code:
A1
Abstract:
Provided are a zoom lens assembly, image capture device, and camera, wherein the zoom lens assembly comprises a plurality of lens groups which are configured of at least one lens element, and further comprises, in order from the object side to the image capture side, a first lens group having a positive power, and at least one successive lens group. When zooming from a wide-angle end to a telescopic end during photography, the interval between the first lens group and the successive lens group changes, and at least one lens element of all of the lens elements which configure the lens assembly satisfies the conditions ((φ1Gg -φ1GF) + 0.0018 xφ1Gd) / (φ1GF - φ1GC) > 0.8978, and fT / fW > 10.5, where φ1Gn is the refraction of the first lens group for n lines, fW is the focal length of the total assembly in the wide-angle end, and fT is the focal length of the total assembly in the telescopic end.
