DIGITAL TELE CONVERTER*
Some PowerShot models incorporate a digital tele converter
for shooting subjects at great distances without mounting
a separate tele converter lens. Users can select one of two
magnification levels from the menu.
Features
SAFETY ZOOM*
A tele-converter effect is created digitally by shifting the angle of view
* Not on all models.
The Safety Zoom
feature on select
PowerShot cam-
eras lets the user
set a minimum
acceptable
megapixel count
for the digital
zoom.
The zoom pauses
at the end of the
Safety Zoom
rather than at the
end of the optical
zoom range.
SAFETY SHIFT*
PowerShot cameras equipped with Safety Shift can adjust shutter
speed or aperture values automatically if necessary when the
camera is set to Tv or Av mode. This provides enhanced creative
control.
SAFETY FE*
Safety FE (which can be disabled) makes automatic adjustments
to prevent over/under exposed flash shots when shooting in
manual mode.
SAFETY MF*
After focusing the camera in manual mode, simply depress
the shutter button half-way and the camera will automatically
perform a fine adjustment for perfect focus. Safety MF can also
be disabled for complete manual control.
AUTO ISO SHIFT*
In general, sensitivity should be set to the lowest level the ambi-
ent light allows, yet too low a setting can cause camera blurry
photos. PowerShot cameras with Auto ISO Shift provide options
when shooting to prevent unsatisfactory images. In addition to
allowing the user to trigger when the ISO can be changed, Auto
ISO Shift now can automatically adjust sensitivity for the given
light while notifying the photographer.
Innovative Features
Canon’s wide-area AiAF automatically selects one or more
focusing points based on the position of the subject within the
frame. This feature quickly and accurately achieves autofocus
under a wide variety of shooting conditions, even when the
subject is not centered.
You can reduce the size of the AF frame and for some models, you
can position the location of AF frame using the multi-controller or
dial, allowing pin-point focus to be attained. Particularly effective
in macro shots or when focusing on the details of a large subject,
AF Frame Size Modification brings a new level of control to
PowerShot digital cameras.

FLEXIZONE AF/AE*
Using FlexiZone AF/AE, the photographer can freely move the AF
point around the frame, focusing on off-center subjects without
reframing the shot. When using select models equipped with Face
Detection Technology, pressing a button during FlexiZone AF
moves the AF frame manually to the face you want to focus on.
EXPOSURE METERING*
Advanced photographers can select one of three light-metering
modes: evaluative metering, center-weighted average metering, or
spot metering. The spot metering mode enables the measurement
to be tied to the AF point or fixed at the center of the frame.
