the main subject is the closest and most prominent object in the frame and, in

One-Shot, this is where AFPS works best.

The Bonus Feature is that the QCD is now part of your focusing system rather than your

exposure control. The exposure controls are relocated to the AF Point Selection Button.

Hold the selection button in and turn the Main Dial on top of the camera to adjust

exposure compensation in AE modes, or f/stops in Manual mode. The disadvantage of

having these exposure features on the QCD was that it made it very easy to change

exposure settings accidentally. Now, it's just as fast to adjust your exposure settings,

and you are far less likely to change them accidentally.

Action Combo

This combination is most useful for sports and wildlife photographers. Like the Event

Combo, it provides a great deal of versatility and on-the-fly decision-making ability for

photographers, especially for those who shoot rapidly moving subjects in AI Servo AF.

Function

Moves focus activation from the Shutter

release's halfway position (SW-1) to the

camera's rear AE Lock button (*).

C.Fn 4-3 is probably a bit better in rapidly

changing shooting situations like this

because it takes the meter reading in

real-time at the moment of exposure and

can adjust when a subject moves from one

lighting condition to another (e.g., a player

running from shade into the sun). Each

image in a sequence is metered separately.

C.Fn 4-1 will lock the metering for all shots

to the setting used for the first image in the

sequence when using continuous drive. This

is useful if you're shooting a sequence in

even lighting where multiple images may be

printed or shown together.

This expands the AF activation area if

needed in lowered contrast situations.
