Please note that objects with very low contrast (like blank sheets of paper) are difficult to focus. If the
autofocus does not work just move the object slightly.
For special applications the autofocus can also be switched off using the on/off switch (#30 or #46). The
autofocus is also switched off when the manual FOCUS keys (#31 or #45) are used.
