這支 LEICA SUMMILUX 50mm f/1.4 v.2 E43 的後內膠合鏡組(第四鏡組)邊緣有一整圈的脫膠離膠的痕跡，透過複雜但標準化的處理過程，可以將這個問題完美地解決。 

此款鏡頭的後鏡組有兩組膠合鏡組(第四、第五鏡組)，都有發生脫膠離膠的可能。 如果您有此款鏡頭，它的後鏡組有不明的紋路，歡迎跟我聯絡！

The edge of the rear internal doublet (the 4th group) of this LEICA SUMMILUX 50mm f/1.4 v.2 E43 had a problem in elements separation. This problem can be perfectly restored through a complex but standardized process.

The rear part of LEICA SUMMILUX 50mm f/1.4 v.2 E43 has two cemented lens doublet (the 4th and 5th group), both of which may have the elements separation. If you have this lens and it has an unknown pattern on the rear lens assembly, please contact me!
