根据@数码闲聊站以及@智慧皮卡丘的爆料，小米17 Ultra搭载一颗 2 亿像素的潜望式长焦镜头，采用三星 S5KHPE 传感器，支持3倍至7倍的连续光学变 焦，可在全焦段实现近乎无损的画质输出。与此同时，小米还为该长焦模块配备了「可变焦距手机摄像系统」，通过硬件与算法的结合，让用户在不同场景 下都能获得更灵活的构图空间。 （图片来源：微博用户@智慧皮卡丘） 而重点便是这个「可变焦距手机摄像系统」，它与我们传统认知中的倍数变焦不同，从光学原理来看，变焦的本质是通过改变镜头光学系统的焦距，调整被 摄物体在传感器上的成像大小，主要分为光学变焦、数码变焦和混合变焦三类。 近日，小米17 Ultra正式入网，不出意外的话将在元旦前亮相 / 发布。作为超大杯机型，大家最期待的必然是小米17 Ultra的影像表现，根据网友的爆料来看 其将配备「可变长焦」和「可变镜头」两大黑科技。 近些年几乎每一家手机厂商都在影像上下了很大功夫，但大多数都是「一代而亡」，小米17 Ultra的这项黑科技，会「方向正确」吗？ 是花里胡哨，还是正确方向？ 可变焦距手机摄像系统，本质上是对传统光学变焦技术的微型化与优化升级，即通过在极小的机身空 ...
