大家讨论包谷UV镜的鉴别
我见到过两种版本的塑料盒装的多层镀膜包谷UV镜(UV(N)HMC),在包装的细微之处有显著区别:
一、塑料盒背面有两种版本: 1、ENGLISH:Useing high technology development processes, HOYA have produced a UV(N) HMC filter which cuts unwanted light rays in both the UV and IR ranges,without affecting colour balance in the visible spectrum. 2、ENGLISH:Useing high technology development HOYA have produced a UV(N) filter witch absorbs unwanted light rays in the UVB,UVC and IR ranges,without affecting colour balance in the visible spectrum.
二、背面下面的产地标识有两种版本: 1、Made' by Tokina Co,Ltd 2、Made by Tokina Co,Ltd 差前面的一个小逗点 三、盒里面的区别: 1、盒里面有个圆形的纸片,上写 UV Alert ! (UVA:320nm-380nm) ! (UVB:280nm-320nm) 2、没有上述的纸片
请问对包谷UV镜有研究的大虾,这两个版本都是真的?还是一真一假?如果有假,哪种是真的,哪种是假的?质量是否有区别?多大的区别?
