As well as an AE/FE lock button (not shown) the G10 has a customizable shortcut button that can be assigned to control several useful functions including white balance, ND filter and AF lock. The customized functionality only works in a non auto mode (P, TV, AV, M).

繁體中文說明書P.128-129 有說什樣按AF-Lock功能和什麼模式能用。如常用AF-Lock把AFL設定去(S)捷徑鈕會方便些。
