变倍光学系统、光学装置、变倍光学系统的制造方法
Abstract:
本申请的变倍光学系统从物体侧依次具备具有正的光焦度的第1透镜组(G1)、具有负的光焦度的第2透镜组(G2)及具有正的光焦度的第3透镜组(G3)，第1透镜组具备具有负的光焦度的前组(G11)和具有正的光焦度的后组(G12)，通过使前组(G11)移动来进行对焦，第3透镜组(G3)的至少一部分、第1透镜组(G1)或者第2透镜组(G2)作为防抖透镜组在包含与光轴正交的方向分量的方向上移动。
Abstract(English):

The variable power optical system of the present application has, in order from a body side, a first lens group (G1) having a positive refractive power, a second lens group (G2) having a negative refractive power, and a third lens group (G3) having a positive refractive power, wherein: the first lens group has a front group (G11) having a negative refractive power and a rear group (G12) having a positive refractive power; focusing is carried out by moving the front group (G11); and at least a portion of the first lens group (G1), second lens group (G2), or third lens group (G3) moves, as a vibration reduction lens group, in a direction including a direction component that is orthogonal to the optical axis.
