2: For sports photography using focus

prediction in AI Servo AF mode, this

option lets the photographer tem-

porarily stop the focus.

When making manual exposure adjust-

ments, this function lets the photograph-

er choose whether to use the main dial

for adjusting the shutter speed or aper-

ture value. This option is convenient for

studio flash photography where the

shutter speed is kept constant while the

aperture is frequently varied to alter

depth of field and exposure.

This function lets the photographer

input shutter speed and aperture set-

tings in any increment that he or she is

used to. 1/2-stop exposure compensa-

tion settings are also possible, providing

wide flexibility to satisfy various shoot-

ing styles.

This option disables the manual focus-

ing capability of the electronic ring pro-

vided on many USM lenses, eliminating

the possibility of accidentally turning the

ring and shifting the focus after autofo-

cusing is completed.
