CONTAX Carl Zeiss Vario-Sonnar 100-300mm f/4.5-5.6 後膠合鏡組脫膠重新粘合 Re-cementing for rear lens group elements separation

最近一連收到兩支Contax 100-300，問題都是脫膠/離膠，脫膠離膠鏡組的位置都是在後鏡組。我就分別把兩支脫膠的樣子po上來，雖然脫膠離膠的程度和範圍不一樣，但處理的程序都一樣。
處理脫膠離膠時，需要精準的貼合，不然拍出來的照片會無法準確合焦～
最後，當然是順利完成工作，兩支鏡頭都回春了！

In this page, you will see the elements separation happened to the rear cemented lens group of Contax 100-300/4.5-5.6.
Here has two cases with cemented lens group separation, which only differences in the degree of separation and shows different shape of separation, but the treatment processes are all the same.
After the treatment, the lens group restored back to its original perfect condition!
