Registrating and Switching 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.

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

•

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.
