成像镜头系统和具有该成像镜头系统的摄像装置
摘要：
本发明提供成像镜头系统和具有该成像镜头系统的摄像装置。成像镜头系统具有开口光圈以及配置在比开口光圈更靠像侧的像侧透镜组群，像侧透镜组群从开口光圈朝向像侧依次具有负屈光力的第1像侧透镜组、正屈光力的第2像侧透镜组、负屈光力的第3像侧透镜组，第1像侧透镜组、第2像侧透镜组和第3像侧透镜组中的任意一个透镜组是在从无限远物体朝向近距离物体的对焦时沿着光轴移动的对焦透镜组，满足以下的条件式(1)，0.06
摘要（英）：

An image forming lens system includes an aperture stop, and an image-side lens unit group which is disposed on an image side of the aperture stop. The image-side lens unit group includes a first image-side lens unit having a negative refractive power, a second image-side lens unit having a positive refractive power, and a third image-side lens unit having a negative refractive power. Any one of the first image-side lens unit, the second image side lens unit, and the third image-side lens unit is a focusing lens unit which moves along the optical axis at the time of focusing, and the following conditional expression (1) is satisfied: 0.06
