The invention relates to the field of optics, in particular to an unmanned aerial vehicle zoom lens and an unmanned aerial vehicle. The zoom lens of the unmanned aerial vehicle is sequentially composed of a first fixed lens group with positive focal power, a first zoom lens group with negative focal power, a second fixed lens group with positive focal power, a diaphragm, a second zoom lens group with negative focal power, a third fixed lens group with positive focal power and a focusing lens group with negative focal power from an object plane side to an image plane side. The first zoom lens group, the second zoom lens group and the focusing lens group move in the main optical axis direction of the zoom lens of the unmanned aerial vehicle; the zoom lens of the unmanned aerial vehicle meets the following conditional expressions: TTL/ft is less than 0.8; wherein TTL is the total optical length of the zoom lens of the unmanned aerial vehicle, and ft is the focal length of the zoom lens of the unmanned aerial vehicle in a telescopic state. The zoom lens of the unmanned aerial vehicle can be installed in a smaller unmanned aerial vehicle, and can shoot a picture at a farther position, so that the application range of the zoom lens of the unmanned aerial vehicle is expanded.

    本发明涉及光学领域,具体为一种无人机变焦镜头和无人机,所述无人机变焦镜头从物面侧到像面侧依次由正光焦度的第一固定透镜群、负光焦度的第一变倍透镜群、正光焦度的第二固定透镜群、光阑、负光焦度的第二变倍透镜群、正光焦度的第三固定透镜群、负光焦度的聚焦透镜群组成;所述第一变倍透镜群、第二变倍透镜群和聚焦透镜群沿所述无人机变焦镜头的主光轴方向移动;所述无人机变焦镜头满足以下条件式:TTL/ft<0.8;其中,TTL为所述无人机变焦镜头的光学总长,ft为所述无人机变焦镜头的望远状态的焦距。无人机变焦镜头能够安装在较小的无人机内,同时还能够拍摄到较远位置的画面,增加了无人机变焦镜头的适用范围。
