24-70 2.8L 一代DIY維修紀錄
Dec 11th 2013, 04:58

小弟的24-70一代,經小弟多年來當鏡頭蓋狂操猛送之後,已經發生前鏡筒鬆垮垮,對焦似準似不準的狀況,真的搞不清楚是對焦跑掉或是光軸跑掉,某天用最大光圈對著戶外拍了一張相片

放大後 哇靠,這是散景嗎

於是就爬文順便看了一下24-70構造圖,應該是前鏡筒的滑塊掛了,於是不久後就收到這包

拆開看確定是24-70前鏡筒滑塊無誤

準備好工具後開始拆

拆

再拆

滑塊慘不忍睹

換好後再拍一張放大看看,真的好多了

24端測焦一下

24端準焦狀況好像改善了,這支鏡頭又可以陪小弟狂操猛送很久了

更換好滑塊以及清洗上油之後整隻鏡頭的手感又變成滑順綿密了,再也不會有鬆弛感了,這才是L鏡應該有的表現
