    • A lens barrel having an image blur prevention system including an image blur prevention optical system to prevent image blur, and an image blur prevention optical system drive mechanism to move the image blur prevention optical system within a plane that is generally perpendicular to the optical axis of a main optical system. The image blur prevention optical system drive mechanism is arranged around the image blur prevention optical system to most efficiently use the space in the lens barrel. A power transfer shaft, which is connected to a focusing system in the lens barrel, is arranged in parallel to the image blur prevention optical system, and the focusing system is located in front of the image blur prevention optical system so that it does not interfere with the image blur prevention optical system drive mechanism arranged around the image blur prevention optical system. By efficiently using the space in the lens barrel, the assembly and disassembly of the lens barrel is simplified. Further, by preserving space for the image blur prevention optical system, a large lens size may be maintained.
    • 一种具有防止图像模糊的图像模糊防止系统的图像模糊防止系统的镜筒,以及防止图像模糊防止光学系统的驱动机构,其将图像模糊防止光学系统移动到大致垂直于 主要的光学系统。 图像防止光学系统驱动机构设置在图像模糊防止光学系统周围,以最有效地使用镜筒中的空间。 连接到镜筒中的聚焦系统的传送轴与图像防止光学系统平行地布置,并且聚焦系统位于图像防止光学系统的前面,使得其不会干扰 其中图像防止光学系统驱动机构设置在图像防止光学系统周围。 通过有效地使用镜筒中的空间,可以简化镜筒的组装和拆卸。 此外,通过保留图像模糊防止光学系统的空间,可以保持大的透镜尺寸。
