Mamiya APO A 300mm f/2.8 鏡片發霉 鍍膜輕微變質處理 lens element has fungus and coating deterioration treatment

少見的好物！犀利凶猛！
送來處理的問題是對焦鏡組的其中一枚鏡片滿佈霉斑以及輕微鍍膜變質。
霉斑的處置是依照一般清霉的方式處理，輕微鍍膜需使用輕度拋磨技術，將輕微變質霧化的鍍膜層去除，留下剩下的鍍膜，並保持乾淨通透！
經過仔細處理之後，讓原本無法在使用的鏡頭，恢復原本威猛的狀態！ 恭喜它！

A Rare monster!
One element of the focusing group has serious fungus and slight coating deterioration.
Fungus can be cleaned away by normal cleaning process. The coating haze is a kind of coating deterioration, it can be removed by light polishing technique.
After the careful treatment, make this unusable lens back to clean and clear condition!
