APO Model lens has two SLD (Special Low Dispersion) glass elements in the front lens group and one in the rear lens group, the lens has excellent correction of chromatic aberration through the entire zoom range.

相信沒有APO金色字那支跟本上就沒有APO這三個英文字，鏡咀應該同時沒有紅圈。

這支鏡表示她不是APO鏡，即沒有超低色散鏡片。

我係二手區見倒 apo version 只有 DG 是金色.

這支鏡有紅圈，確實是APO版。

但相信是水貨，我在韓國的官方網站找到這支鏡頭。
