LEICA LEITZ SUMMILUX-R 50mm f/1.4 v.1 全鏡整理 Full CLA

這支鏡頭Leica R 50/1.4 送來時，外觀還不錯，不過鏡片很髒入塵嚴重，也有嚴重的發霉。對焦環很緊很不順。
拆鏡後發現鏡身內的很髒，必須將大部份零件拆解開來細部清理讓它恢復內外皆乾淨。唯有內部零件乾淨，對焦螺紋再重新上潤滑油時才不會吃進髒東西。
機械部分之外，光學部分也是每片鏡片都仔細清理。雖然嚴重的霉有在鏡片上留下一些霉疤，不過至少清理乾淨後，適當保存就不會再長霉，鏡片也藉由完整的清理，得以恢復良好的工作狀態。
全鏡整理不難，只是必須花費比一般清潔保養更多的時間來處理。

This Leica R 50/1.4 v.1 comes with good appearance, other than that, the internal condition is not so good. The glasses have heavy dust and fungus, the focusing ring is tight and works unsmoothly.
I made a full CLA to this lens because the mechanical parts of the lens is really dirty internally. Most of the parts need to be cleaned completely to ensure the new grease works well with the moving parts.
Each glass need to be cleaned carefully to restore its original optical performance.
Full CLA is not a hard task, but a labor intensive work!
