HOW TO USE AUTOFOCUS

Position the photographic subject within the centre of the composition and press the shutter button “half-way”.

If autofocus is selected, the focusing point will be illuminated in green. (At the same time, the auto focus lamp will be illuminated in green.)

If autofocus cannot set correctly, the focusing point will blink. (At the same time, the auto focus lamp will blink in red)

When setting AF mode to normal autofocus (without an icon), the focusing distance is from 28cm to infinity. It is possible

to change AF mode to LIMIT mode ( is displayed) by

pressing the button. In LIMIT mode, the focusing distance will be from 1m to infinity and the AF speed will be faster.

Although your camera is equipped with highly precise AF system, in some cases autofocus cannot set correctly.
