這支 Mamiya-Sekor 80mm f/1.9 的後內膠合鏡組有霧狀脫膠離膠的問題，拍照成像是低反差，特別是逆光的環境下 照片都是霧矇矇的。依照標準的脫膠離膠處理程序，將原本黏合在一起的兩枚鏡片分開 並徹底清潔乾淨之後，精準的重新黏合，便可將問題解決，讓鏡片恢復乾淨通透。 最後兩張測試照 可以清楚地看到 維修前後 在逆光環境下的顯著差別

The rear internal doublet of this Mamiya-Sekor 80mm f/1.9 has a foggy elements separation issue. The photos taken with this lens have low contrast, especially in backlit environments where the pictures appear hazy. According to the standard re-cementing procedure for dealing with the element separation, taking apart the two originally bonded lens elements, thoroughly cleaning them, and then precisely re-cementing them can resolve the problem, restoring the lens to its clear and transparent state. The last two test photos clearly show the significant difference in backlit environments before and after the repair.
