Description
第２レンズ群Ｇ２は第１レンズ群Ｇ１に比べ大幅に光線径が低くなり、防振群として用いることで防振群の軽量化に適する。更に第２レンズ群Ｇ２を物体側から順に２ａ群Ｇ２ａと２ｂ群Ｇ２ｂに分割し、像側に配される光線径のより低い２ｂ群Ｇ２ｂのみを防振に用いることにより防振群の更なる軽量化に適する。
The second lens group G2 has a significantly smaller beam diameter than the first lens group G1, and is suitable for reducing the weight of the image stabilizing group by using it as an image stabilizing group. Further, the second lens group G2 is divided into the 2a group G2a and the 2b group G2b in order from the object side, and only the 2b group G2b having a lower light beam diameter arranged on the image side is used for image stabilization. Suitable for weight reduction.
