Setting the zoom position manually
When you want to change the zoom position to one that does not match the focal
length, you should adjust the zoom position manually.
A small “ ” above the “ZOOM” indication appears on the LCD panel while
manually setting the zoom position.
Press the [ZOOM] button, then turn the selector dial to set the zoom position.
Turn the selector dial clockwise to increase the value, and counter-clockwise to
decrease the value.
You can also adjust the zoom position by pressing the [ZOOM] button. In this case, the
value increases every time you press the [ZOOM] button. Note that the zoom position
changes to the widest position next to the most telephoto position.

on or off.
An “
