CONTAX Carl Zeiss Planar 100mm f/2.0 T* 對焦環進海砂清潔潤滑 Cleaning sand from the focusing helicoids

這支鏡頭的主人帶著它到海邊,鏡頭不小心掉到海灘上,撿起來後轉動對焦環,發現沙沙卡卡的,就送來給我清潔
我拆鏡後發現,鏡片都乾淨,但對焦螺紋和內鏡筒壁有砂子,將砂子清潔乾淨後,重新潤滑螺紋,便完成這次的維修

The owner went to the beach and the lens fell down accidentally, then he found something wrong when turning the focusing ring.
When I took apart the lens, I saw sand on the focusing helicoids and the internal lens parts, the internal glasses were clean. So I cleaned all the sand and made a lubrication with new grease on the focusing helicoid.
