Using the Optical Viewfinder to Shoot
The camera is equipped with an optical viewfinder.
• Align the square brackets (autofocus metering
field) inside the viewfinder on the primary
subject to compose the image.
• The viewfinder has a field of vision of
approximately 82% of the actual shooting
image.

The Parallax Phenomenon
Please note that the actual image may differ from the image seen in the optical
viewfinder due to the physical separation between the viewfinder and lens. This is
called the parallax phenomenon and is more noticeable the closer the subject is to
the lens. In some cases, portions of images shot up close that appear in the
viewfinder will not appear in the recorded image. You are recommended to use the
LCD monitor to shoot images up close.
Shooting with an Off-Center AF Frame Selected
You should always use the LCD monitor to compose images when you have selected
an off-center AF frame (p. 71).
