VOIGTLANDER NOKTON 50mm f/1.5 前鏡組脫膠/離膠 重新黏合 Front cemented lens group separation, Re-cementing

這支經典的老福時常出現一個問題，就是這支鏡頭保存到現在，常會出現脫膠/離膠的問題，不管是前膠合鏡組或是後膠合鏡組，都會有這問題。 處理的方式就是把脫膠/離膠的鏡組分開，在用現代的光學膠重新黏合來解決這問題。
脫膠/離膠的問題 我處理起來駕輕就熟，不會有任何差錯。
這篇這支是前膠合鏡組有脫膠/離膠的問題。處理過程雖然繁複，不過問題是可以完美解決的！

This Legendary Nokton lens always faces a typical problem with its cemented front and rear lens group may has issue of separation. The treatment process is to take apart the cemented group into original two piece of glass, then re-cementing with perfect collimation.
I've dealt with separation for hundreds cases with great result.
This case has the separation to its front cemented group, even the treatment process is quite complex, but the result is perfect!
