Claims (7)
無限遠物体から近距離物体へのフォーカスに際して該第２レンズ群は像側へ、該第３レンズ群は物体側へ移動する撮影レンズであって、
第１レンズ群は光軸と垂直方向の成分を持つように移動して、該撮影レンズが形成する像を変位させる負の屈折力のレンズ成分を有することを特徴とする撮影レンズ。 In order from the object side to the image side, a first lens unit having a positive refractive power, a second lens unit having a negative refractive power, a third lens unit having positive refractive power, and a fourth lens unit having a negative refractive power,
The second lens group is a photographic lens that moves toward the image side and the third lens group moves toward the object side when focusing from an object at infinity to a near object,
The first lens group has a negative refractive power lens component that moves so as to have a component perpendicular to the optical axis and displaces an image formed by the photographing lens.
第１レンズ群は、光軸と垂直方向の成分を持つように移動して、該撮影レンズが形成する像を変位させる負の屈折力のレンズ成分を有することを特徴とする撮影レンズ。 In order from the object side to the image side, a first lens unit having a positive refractive power, a second lens unit having a negative refractive power, a third lens unit having a positive refractive power, focusing from infinity to a close object In this case, the first lens group, the second lens group, and the third lens group are photographic lenses that move independently to the object side,
The first lens group includes a lens component having a negative refractive power that moves so as to have a component perpendicular to the optical axis and displaces an image formed by the photographing lens.
−２．１＜ｆｎ／ｆ＜−１
なる条件を満足することを特徴とする請求項１，２又は３の撮影レンズ。 When the focal length of the lens component having the negative refractive power is fn and the focal length of the entire system is f, −2.1 <fn / f <−1
The photographic lens according to claim 1, 2 or 3, wherein the following condition is satisfied.
