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 “

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 “
