Steinheil Quinar 135mm f/2.8 鍍膜退化脫膜 拋光處理 coating loss polishing treatment

鏡頭的主人說希望可以讓鏡片恢復乾淨透亮，他接受我建議的唯一處理方法--鍍膜拋光
這支有Steinheil鏡頭典型的鍍膜脫膜問題。 拋光處理，就是把目前在鏡片上剩下的雜亂不均勻的鍍膜拋掉，讓鏡片回復清透。

鍍膜拋除並不會影響畫質，也不會改變鏡片的曲度。 成像品質與完好的鏡頭一樣良好，不會有什麼不同。  當然，這種高難度的工作需要經驗豐富的手藝，不然會搞砸的～

這支拋光的結果使這支鏡頭煥然一新，是完美的處理！

下一篇將介紹一個被別人搞砸，但被我救回來的案例！


The owner wanted the lens to be clean and clear again, and accepted the only way I proposed -- coating polishing.

Coating polishing treatment won't affect the image quality in anyway, and won't alter the curve of the glass. This treatment need experienced craftsmanship, otherwise will screw it up~

The result shows here is perfect, lens clear again!

Next page will show you a case that was screwed up by someone, but rescued by me ^_^
