几十块钱的镜头今天被无意改成泡泡镜了
本帖最后由 三WWW 于 2022-11-22 17:31 编辑这颗镜头是十多年前在论坛收的，好像是50多，红色镀膜，当时拿来改了调焦筒和光圈后就一直扔在防潮箱里面，镜头分辨率很高，焦距好像是90左右，固定光圈大概2.8；
前几天重新买了个调焦筒装上可以拍1:1的微距，逆光基本见光死，拆开看了，4枚4组镜片，都没有涂消光漆，昨天拆开挨个用油性马克笔涂了，逆光好了不少，里面的固定光孔比较小，大概直径1cm多，今天早上硬是用锉刀加手钻扩展到1.5左右，但高光边缘溢出，锐度还是惊人的，下午出门试了下，发现居然有泡泡焦外，很是惊喜，锐度好的泡泡镜很难得;P

今天仔细观察，该镜头是六片四组，前后对称各三片。
