较佳地，该摄像镜头满足下列关系式：T23/T12<0.2；其中，T23为该第二透镜L2和该第三透镜L3的轴上间隔距离；T12为该第一透镜L1和该第二透镜L2的轴上间隔距离。
满足上式要求的摄像镜头有利于减小各透镜间的间距，缩短了摄像镜头的总长度，进一步保证摄像镜头的小型化。
较佳地，该摄像镜头满足下列关系式：0.5<R2/R3<1.5；其中，R2为该第二透镜L2的物侧面S3的曲率半径；R3为该第三透镜L3的物侧面S5的曲率半径。
满足上式要求的摄像镜头，其中心到边缘的整体像质比较均匀，有利于提升成像品质。
较佳地，该摄像镜头满足下列关系式：0<Dr5r8/TTL<0.5；其中，Dr5r8为该第三透镜L3的物侧面S5至该第四透镜L4的像侧面S8的轴上距离；TTL为该第一透镜L1的物侧面S1至成像面S15的轴上距离。
满足上式要求的摄像镜头可使摄像镜头保持小型化及简易的特性，以便于搭载在轻薄可携式的电子产品上。
较佳地，该摄像镜头满足下列关系式：1<DT12/DT21<2；其中，DT12为该第一透镜L1的像侧面S2的有效半径；DT21为该第二透镜L2的物侧面S3的有效半径。
满足上式要求的摄像镜头有利于均匀分配透镜的口径，有效减小摄像镜头的体积，且易于透镜组装，并可降低摄像镜头的敏感性。
较佳地，该摄像镜头满足下列关系式：-2<f6/f<-0.8；其中，f6为该第六透镜L6的有效焦距；f为该摄像镜头的有效焦距。
满足上式要求的摄像镜头有利于在实现摄像镜头的小型化的同时，可使得摄像镜头的光线角度平缓，降低摄像镜头的公差敏感度，使摄像镜头易于加工及组装。
较佳地，该第三透镜L3的物侧面S5为凸面，该第四透镜L4的物侧面S7为凸面， 该第四透镜L4的像侧面S8为凸面。
成像时，光线穿过六片透镜后经过具有物侧表面S13及像侧表面S14的滤光片L7后成像于成像面S15。
在某些实施例中，第一透镜L1、第二透镜L2、第三透镜L3、第四透镜L4、第五透镜L5及第六透镜L6都为非球面透镜。
非球面的面形由以下公式决定：
