最近買了 Canon EF 24mm F1.4 L II USM 配上 1D Mark IV , 就發現近距離 測焦準確 , 但與被攝物隔 一公尺以上 , 對焦點就前移的非常厲害 , 幾乎九成都跑焦. 不論是縮小光圈 , 調快快門 , 架腳架拍 ,中央點對焦 ,大好的天氣也是照偏不誤. The far-heavier and far-more-expensive Canon EF 24mm f/1.4L II USM Lens is in a different league with its 2-stop aperture allowing 4x as much light to reach the sensor and creating a much stronger background blur. If I had to rely on a lens to perform when I needed it to, the L lens would get my vote. HWL7w2.
