[100905] Re: Sigma 24-105 f/4 DG OS ??
日前購入此鏡

有些小小的抱怨，就是當變焦到105mm時與廣角端(大約就24mm)對焦尺上顯示的合焦距離是不同的

像是，當105mm準焦時對焦尺若是3m，則24mm準焦的對焦距離就不會是3m，需要重新對焦，不然拍出來就是糊的

現在DSLR對比對焦已非常好用(最起碼在暗處很準焦)，但在相當暗的場合，廣角相位對焦往往不怎麼靈光，最少我的D600是這樣的，還不如先變焦到望遠找對比明顯的物體確定合焦

再者，若24mm與105mm對焦尺顯示的合焦距離與鏡頭實際上對到的距離不同，那留它又有何用?? 不要忘了，Sigma自己把這隻歸入『Art』系列，這實在有點諷刺

不知道是小弟鏡頭用太少還是怎樣，但這真的讓人很不習慣，就算是便宜的kit鏡18-55都不會有這種特性

恒伸的技術回答很直白，說這就是設計不是瑕疵，不錯，但是當初店家的回答就太離譜了，扯到什麼法蘭距什麼光軸什麼不能讓光轉彎巴拉巴拉，反而讓人起疑心


總之要買這隻的版友知道一下就好了
