Abstract

　高画素に対応した小型で廉価な撮影レンズを提供する。 　被写体側から順に、第一レンズ(L1)、開口絞り(S1)、第二レンズ(L2)、第三レンズ(L3)の順に構成される撮影レンズに係る。第一レンズ(L1)は、被写体側に凸面を向けた正のパワーを持ち、被写体側を球面とするとともに、被写体とは反対側である像側を近軸から周辺に掛けて変曲点を持たない非球面とするメニスカスレンズである。第二レンズ(L2)は、像側に凸面を向けた負のパワーを持ち、且つ両面を非球面とするメニスカスレンズである。第三レンズ(L3)は、被写体側に凸面を向けた正のパワーを持ち、且つ両面を非球面とするメニスカスレンズである。
