请问：你用了几面的非球面啊？
单看MTF值还是不错的耶？

xiaoniu

看样子用了四个非球面,不知是不是1G2P......

luaim

大概是5个非球面，除了第一面不是。

poon

我觉得应该是不能使用的，虽然mtf是比较高，实际做出来的就不是这个了。
不过设计得非常好了。

不知道MTF VS. FLD 如何. 还有畸变.
第一片边厚太薄.

sunny5430

It's a nice performance.
I also think that it's used 4 or 5  asphere.

非球面设计得好奇怪呀！加工会不会有问题呢

设计光学

请问?G?P中G是指GLASS,那么P是指什么啊?

还有看一本书中,SING2O6A,不知道2和6具体的含义啊?

求战友帮忙啊!!!

镜头设计师

奇怪，这个镜头我很早以前就设计过，你怎么也会？是手机上用的，４个非球面如果我没记错的话，不过你的MTF算蛮高的
