✦
Focusing distance range selec-
tion switch. This switch deter-
mines and limits the range that the
lens uses when seeking focus to
speed up autofocusing. The focus-
ing distance range options vary by
lens.
✦
Image stabilizer switch. This
switch turns optical image stabi-
lization on or off. Optical Image
Stabilization (IS) corrects vibrations
at any angle when handholding
the camera and lens. IS lenses typi-
cally allow sharp handheld images
up to two or more f-stops over the
lens’s maximum aperture.
✦
Stabilizer mode switch. Offered
on some telephoto lenses, this
switch has two modes: one mode
for standard shooting and one
mode for vibration correction when
panning at right angles to the cam-
era’s panning movement.
✦
Focusing ring and zoom ring.
The focusing ring can be used at
any time regardless of focusing
mode. On zoom lenses, the zoom
ring zooms the lens in or out to
the focal lengths marked on the
ring.
✦
Distance scale and infinity com-
pensation mark. This shows the
lens’s minimum focusing distance
to infinity. The infinity compensation
mark compensates for shifting the
infinity focus point resulting from
changes in temperature. You can
set the distance scale slightly past
the infinity mark to compensate.
Setting Up the Rebel
XSi/450D
Setting up the Rebel XSi/450D is the first
step in getting pictures from the camera that
you’ll treasure for years to come. Although
this chapter offers important pointers on
setting up your camera, ultimately the best
way to get great pictures from the Rebel
XSi/450D is to use the settings and evaluate
the images. Unlike paying for film and
prints, the pictures that you take with the
Rebel XSi/450D are at no additional charge,
so to speak. This gives you the freedom to
explore different camera settings until you
get pictures with a combination of color, sat-
uration, and contrast that creates great
prints.

If You Need to Start Over
If you’re new to digital SLR cameras, you may avoid changing camera settings for fear
that it will “mess up” the pictures you’re getting, or that you’ll forget how to reset the
camera if you don’t like the changes you’ve made. Canon provides a reset option,
which means that you can revert to the original camera settings to have a fresh start
at any time.
To reset the camera to the default settings, just press the Menu button, press the right
cross key to select the Set-up 3 (yellow) menu, and then press the down cross key to
select Clear settings. Press the Set button. On the Clear settings screen, press the up
or down cross key to select Clear all camera settings, and then press the Set button.
Press the right cross key to select OK, and then press the Set button.
