Using The Viewfinder - Canon PowerShot SD100 User Manual

Using the Viewfinder

The viewfinder can be used to conserve power by setting the LCD monitor
to Off (p. 34) while shooting.
About the Autofocus Function
This camera employs AiAF (artificial intelligence autofocus)
technology which uses a broad metering field to calculate the focal
distance with high precision. It delivers a crisp focus even when the
photographic subject is slightly off-center.
The AiAF function can be turned off so that the autofocus is metered
from a fixed AF frame at the center of the field to accommodate
difficult shooting conditions (p. 80).
Image Seen in Viewfinder vs. Recorded Image
Usually the recorded image is wider than the image seen in the
viewfinder. Confirm the actual image size with the LCD monitor.
The image recorded may differ from the image seen in the viewfinder
due to the distance between the viewfinder and lens (especially with
close-ups). If you use the viewfinder to take close-up shots, portions of
the close-up subject may not appear in the recorded image. Use the
LCD monitor when taking close-up shots.
