AUTO FOCUS

The camcorder’s Full Range AF system offers continuous shooting ability from close-up (as close as approx. 1.5 cm to the subject) to infinity. However, correct focus may not be obtainable in the situations listed below (in these cases use manual focusing):

•When two subjects overlap in the same scene. •When illumination is low.*

•When the subject has no contrast (difference in bright- ness and darkness), such as a flat, one-color wall, or a clear, blue sky.*

•When a dark object is barely visible in the viewfinder.* •When the scene contains minute patterns or identical

patterns that are regularly repeated.

•When the scene is affected by sunbeams or light reflecting off the surface of a body of water.

•When shooting a scene with a high-contrast background.

*During Manual Focus, the following low-contrast warnings appear blinking: , , and

NOTES:

If the lens is smeared or blurred, accurate focusing is not possible. Keep the lens clean, wiping with a piece of soft cloth if it gets dirty. When condensation occurs, wipe with a soft cloth or wait for it to dry naturally.

When shooting a subject close to the lens, zoom-out first (pg. 20). If zoomed-in in the auto focus mode, the camcorder could automatically zoom out depending on

the distance between the camcorder and the subject. When “TELE MACRO” (pg. 27) is activated, the camcorder will not zoom out automatically.
