C.Fn-18-2

Registrating and Switching AF Point

Switching to the Registered AF Point

Normally, you press the <> button and <> button simultaneously to switch to the registered AF point. However, with C.Fn-18-1/2 (→p.138), you can just press the <> button to switch to the registered AF point. See “Setting a Custom Function” on page 132.

(1) Press the <> button and <> button simultaneously.

• This is the default method with C.Fn-18-0.

(2) Press only the <> button to switch to the registered AF point.

C.Fn-18-1 (→138)

(3) Switch to the registered AF point only while pressing the <> button.

(→138)

•When the <> button is released, it will return to the original AF point.

•If no AF point has been registered, the above steps will switch it to the center AF

point.

•If you set or cancel C.Fn-13, the center AF point will become the registered AF point. This does not apply if you change C.Fn-13-1 to C.Fn-13-2 (or vice versa). The registered AF point will not change in this case.

If C.Fn-18-1/2 and C.Fn-04-1/3 have been set, you can press only the <> button to switch to the registered AF point and start autofocusing at the same time.
