IMAGING LENS, OPTICAL DEVICE THEREOF, AND METHOD FOR MANUFACTURING IMAGING LENS
Abstract:
An imaging lens includes at least a first positive lens group, a first negative lens group that moves during focusing, a second positive lens group that moves during focusing, a second negative lens group that can move in a direction substantially vertical to an optical axis, and a positive lens group, which are disposed in order from an object, wherein a condition of an expression, which is 2.0
Abstract(Chinese):

成像透镜包括至少第一正透镜组，在聚焦期间移动的第一负透镜组，在聚焦期间移动的第二正透镜组，可在基本垂直于光轴的方向上移动的第二负透镜组， 和正透镜组，其中满足表达式为2.0 <（ - f4）/ d34 <20.8的条件，其中f4是第二负透镜组的焦距 （振动组），其可以在基本上垂直于光轴的方向上移动，并且d34是在最接近透镜组的图像设置的透镜表面（第二正面）之间的在无限远聚焦时在光轴上的空气距离 透镜组，在本实施例的情况下），其设置在第二负透镜组的物体侧，该第二负透镜组可沿基本上垂直于光轴的方向移动;以及透镜表面，最靠近该阴性物体设置 e透镜组，其可以在基本上垂直于光轴的方向上移动。
