Abstract
【解決手段】 開口絞りに対して最も物体側に負の屈折力の第1レンズ群が配置され、該開口絞りに対し、像側に少なくとも1つの正の屈折力のレンズ群が配置され、各々のレンズ群間隔を変化させてズーミングを行うズームレンズであって、
所定の条件を満足するアッベ数と部分分散比の材料より成る光学素子を少なくとも1つ有し、
該光学素子の焦点距離fN、望遠端での該開口絞りから該光学素子までの距離Lt、望遠端の光学全長Tt、広角端と望遠端の焦点距離fw、ft等を適切に設定したこと。

軸上色収差における2次スペクトルの発生するメカニズムは次のように考えられる。正レンズで発生する軸上色収差は、短波長側で急激にアンダーになる性質がある。
尚、各実施例において、第1レンズ群L1の物体側や最終レンズ群の像側に光学フィルターや屈折力の小さなレンズ群を付加しても良い。
