LEICA SUMMICRON-M 50mm f/2.0 E39 現行版 脫膠 重新粘合 6th Treatment Lens Separation; Re-cementing Re-gluing

這支是現行版的M50/2 E39銀鏡，鏡況不太好，主要問題是有兩組膠合鏡片都脫膠了，需要處理，另外就是有些鏡片發霉需要清理。
一隻鏡頭有兩組脫膠，算是大病，處理起來要格外小心。再加上這支全開光圈就有很好的表現，重新粘合時只要有絲毫誤差，全開光圈拍攝時的畫質就會大受影響～ 處理起來可是戰戰兢兢！
最後，問題順利解決，修復後試拍結果非常滿意～ 全開光圈試拍犀利完美，細節清清楚楚！
以下附上幾張修復後的試拍照，請參考！
