HASSELBLAD CFE 40mm f/4.0 IF 內鏡片雙面鍍膜變質起霧拋光處理 One element two surfaces haze caused by coating deterioration

這支哈蘇CFE 40/4 IF 算是很新的鏡頭，不過它有一片鏡片的兩個面的鍍膜都變質起霧了。
鍍膜變質霧化的處理方式就是把變質的鍍膜拋除，這支有問題的那片鏡片的兩面都有問題，所以前後兩個面的鍍膜都必須拋除。
把有問題的鍍膜拋除掉，鏡片就恢復乾淨通透的狀態，成像也就可以恢復原有犀利的品質！

The Hasselblad CFE 40/4 IF lens is a relative new lens in its family, but this one gat a serious problem that there has an independent internal lens element suffering from coating deterioration that make the glass looks hazy.
The way to rescue a lens with coating issue is to make a polishing treatment to remove the deteriorated coating.
One of the internal element got two surfaces coating issue, so it need to remove the whole coating of this glass.
After the polishing treatment completed, the lens looks clean and clear again and it provides the superb performance as its original condition.
