我收到鏡頭後，立刻完全拆解，將所有零件以及每一片鏡片仔細清理乾淨，在確認沒有任何水痕之後，重新組裝。
對焦環螺紋上的潤滑油必須先清除乾淨，再重新上油潤滑。
鏡身大部份機械結構組裝好，確認動作沒問題之後，再安裝鏡片。 鏡片安裝回去之前，必須確保完全沒有水漬痕跡，以避免水漬痕殘留在鏡片上會傷害鍍膜。
進水的鏡頭理應都要全鏡拆解，非常耗時費工！
最後，恭喜這支鏡頭重生！
Here is an urgent case, this lens dropped into water and the water penetrated into the most inner part of the lens, so need fully disassembling for cleaning.
For a flooded lens, the most important is to make sure that all the undesired water/moisture need to be removed before re-assembling.
The original grease on the focusing helicoid need to be removed first then apply new grease. Each piece of glass cannot show any sign of water marks.
Restoring a flooded lens is a hard work, its a time- and energy-consuming task!
