LEICA SUMMILUX-M 75mm f/1.4 對焦環對焦螺紋重新潤滑 Lubricating the focusing helicoids

這支LEICA SUMMILUX-M 75mm f/1.4的對焦環在轉動的時候手感不佳有點緊，影響拍攝。 對焦結構拆解後，以適當的油脂重新潤滑對焦螺紋，使其恢復最好的工作狀態。  這款鏡頭的對焦環轉動手感目前普遍都蠻重的，如果你想要改善手邊鏡頭的這類問題，歡迎跟我聯絡！

The focus ring of this LEICA SUMMILUX-M 75mm f/1.4 feels tight when turned, affecting the shooting experience. After disassembling the focusing parts, I lubricated the focus helicoids with appropriate grease to bring it back to optimal working condition.

Currently, many Leica SUMMILUX-M 75mm f/1.4 lenses have issues with the focusing ring feeling stiff to turn. If you would like to improve this issue with your lens, feel free to contact me!
