對焦、變焦與景深

對焦前，請先轉動變焦環5調整焦距，直至取景器中獲得令人滿意的構圖。

如果相機具有景深預覽（縮小光圈）按鈕或控制桿，則可以通過相機觀景器預覽景深。

•由於本鏡頭的光學特性原因，在較近的對焦距離範圍內，焦距會略有減小。

•距離尺並不表示主體和相機之間的精確距離。數值是近似值，只能作為一般參考。當拍攝遠處的風景時，景深可能會影響操作，因此相機對焦的位置可能比無限遠稍近一些。

自動對焦和手控補償（M/A模式）

1將對焦模式開關d設定在M/A。

2可以使用自動對焦，但通過半按住快門釋放按鈕，同時轉動獨立對焦環，或者在配備AF-ON按鈕的相機上按此按鈕，則可以使自動對焦操作無效。

3再半按一次快門釋放按鈕或再按一次AF-ON按鈕即可取消手動對焦並恢復自動對焦。
