小弟係單反新手.但都知道什麼叫焦點.剛買了400d機身和1支17-40L發覺焦點後移情況嚴重.之後經各方了解.原來其它70-200mm就更離普.小兄想問下各位師兄.canon有無一支變焦鏡比較好D無甘容易走焦呢？

Out-focus may be the body problem, not only the lens problem. I have Canon 300D, out-focus very seriously.

你用定焦鏡一試就知道分別.400D機身都換左二次.結果都係一樣.但一換左支任何定焦鏡.走焦情況就最無發生

解決辨法只有一個,
就係襯你部機同支鏡仲新仲有d 價, 拿拿聲去二手區放鬼左許 la. 快d 忙記呢d 唔開心野
仲有 ,c兄點解買之前唔睇下呢個post 先 呢?

認真請教：CAN0N 既走焦問題
