NOTES
• Changing the optical zoom factor also affects the lens
aperture value.
• The lens aperture value indicated on the camera is the
aperture when optical zoom is 1X. Using a higher opti-
cal zoom setting results in a higher aperture value
(smaller aperture).
• Use of a tripod is recommended for telephoto shots to
avoid blurring of the image due to camera movement.
