重新设置自动对焦按钮,这会让你在实际拍摄的时候大大节约时间。如果你留心观察体育摄影师,就会发现他们的右手大拇指总是在相机背部徘徊,而食指是会放在快门释放按钮下的。这跟我们一般只使用食指半按快门的方式非常不一样,他们使用了我们多数人都不用的按键“AF-ON”。AF-ON的优点是:省去调整AF模式(one shot,ai,ai servo)的麻烦,不用浪费时间去修改对焦模式。同时拍摄静止物体和运动物体的时候,更改AF模式很麻烦。而连续对焦是没法用来拍摄静止物体的,如果你在对焦之后再调整构 Reset the AF button, which will save you time when actually shooting. If you look closely at sports photographers, you notice that their right thumbs are always hovering over the back of the camera, with the index finger just under the shutter release button. This is very different from the way we normally only use the index finger halfway through the shutter, and they use the key “AF-ON” that most of us do not use. The advantages of AF-ON are: eliminating the need to adjust the AF mode (one shot, ai, ai servo) without wasting time modifying the focus mode. When shooting still and moving objects at the same time, changing the AF mode is troublesome. The continuous focus is not used to capture still objects, if you adjust the structure after focusing
