以下对本申请的特征、原理和其他方面进行详细描述。

在示例性实施方式中，第五透镜的像侧面的曲率半径R10与第五透镜的有效焦距f5可满足：-0.7<R10/f5<0，例如，-0.7<R10/f5<-0.15。合理设置第五透镜的像侧面的曲率半径与第五透镜的有效焦距的比例关系，有利于实现前组透镜与后组透镜的衔接以及光学系统的长焦特性。
在示例性实施方式中，第一透镜和第二透镜在光轴上的间隔距离T12、第二透镜和第三透镜在光轴上的间隔距离T23、第三透镜和第四透镜在光轴上的间隔距离T34、第五透镜和第六透镜在光轴上的间隔距离T56以及第六透镜和第七透镜在光轴上的间隔距离T67可满足：(T12+T23+T34)/(T56+T67)<0.4，例如，0.1<(T12+T23+T34)/(T56+T67)<0.4。合理设置各透镜在光轴上的空间分布，有效控制各透镜之间的间隔距离，有利于光学系统更好地承接光焦度的变化，有效减小光学系统的轴向色差。

在示例性实施方式中，光学成像镜头还包括设置在第一透镜与第二透镜之间的光阑。光阑至光学成像镜头的成像面在光轴上的间距SL与第一透镜的物侧面至光学成像镜头的成像面在光轴上的距离TTL可满足：0.7<SL/TTL<0.9。合理设置光阑至光学成像镜头的成像面在光轴上的间距与第一透镜的物侧面至光学成像镜头的成像面在光轴上的距离的比例关系，有利于镜头具有大光圈特性的同时，实现小型化。
在示例性实施方式中，第一透镜至第五透镜中各透镜的最大有效半径可按照第一透镜至第五透镜的次序依次递减。这样的设置有利于实现前组透镜的聚焦特性。
在示例性实施方式中，第四透镜的物侧面的最大有效半径D41与第五透镜的像侧面的最大有效半径D52可满足：1.2<DT41/DT52<1.6。第四透镜的物侧面的最大有效半径与第五透镜的像侧面的最大有效半径满足上述比例关系，有利于光学成像镜头更好地承接光焦度的变化，实现系统的长焦特性。
在示例性实施方式中，第二透镜的像侧面和光轴的交点至第二透镜的像侧面的有效半径顶点的轴上距离SAG22与第三透镜的物侧面和光轴的交点至第三透镜的物侧面的有效半径顶点的轴上距离SAG31满足：0.8<SAG22/SAG31<1.4。合理设置第二透镜的像侧面的矢高与第三透镜的物侧面的矢高的比例关系，有利于实现光学系统聚焦特性的同时，减小光学系统的球差和色球差。

在示例性实施方式中，光学成像镜头的总有效焦距f与光学成像镜头的入瞳直径EPD可满足：f/EPD<1.5，例如，f/EPD<1.3。满足f/EPD<1.3，可实现大孔径成像系统。
在示例性实施方式中，光学成像镜头的最大半视场角Semi-FOV可满足：tan(Semi-FOV)<0.55，例如，tan(Semi-FOV)<0.50。同时满足tan(Semi-FOV)<0.55和f/EPD<1.3，有利于在保证系统的大光圈特性的同时，实现系统的长焦特性。
可选地，根据本申请的光学成像镜头还可包括用于校正色彩偏差的滤光片和/或用于保护位于成像面上的感光元件的保护玻璃。
根据本申请的光学成像镜头采用七片的非球面透镜，通过不同镜片的搭配和设计，可以获得较高的成像质量。同时，根据本申请的光学成像镜头可以在兼顾长焦超薄的同时具备较大光圈的特性，可以有效突出拍摄主体，从而能够较好地满足人像拍摄的特殊功能。
在示例性实施方式中，各透镜的镜面中的至少一个为非球面镜面，即，第一透镜的物侧面至第七透镜的像侧面中的至少一个镜面为非球面镜面。非球面透镜的特点是：从透镜中心到透镜周边，曲率是连续变化的。与从透镜中心到透镜周边具有恒定曲率的球面透镜不同，非球面透镜具有更佳的曲率半径特性，具有改善歪曲像差及改善像散像差的优点。采用非球面透镜后，能够尽可能地消除在成像的时候出现的像差，从而改善成像质量。可选地，第一透镜、第二透镜、第三透镜、第四透镜、第五透镜、第六透镜和第七透镜中的每个透镜的物侧面和像侧面中的至少一个为非球面镜面。可选地，第一透镜、第二透镜、第三透镜、第四透镜、第五透镜、第六透镜和第七透镜中的每个透镜的物侧面和像侧面均为非球面镜面。

本申请的示例性实施方式还提供一种电子设备，该电子设备包括以上描述的成像装置。
然而，本领域的技术人员应当理解，在未背离本申请要求保护的技术方案的情况下，可改变构成光学成像镜头的透镜数量，来获得本说明书中描述的各个结果和优点。例如，虽然在实施方式中以七个透镜为例进行了描述，但是该光学成像镜头不限于包括七个透镜。如果需要，该光学成像镜头还可包括其它数量的透镜。
