Notes:
• No operation for 10 seconds or more automatically clears the focus position indicator.
• To change the angle of view by moving the zoom adjustment ring, also move the focus lock knob to adjust the focus.
<How to adjust the focus>
• When an auto iris lens is used to shoot a photographic subject, the originally adjusted focus may be slightly off depending
on the iris state resulting from the focal depth of the lens. In such a case, open the aperture by darkening the subject as
much as possible in the same way of taking picture, and then adjust the focus. Defocus can be prevented.
Use of "ABF" of "BACK-FOCUS SETUP" in the setup menu (
☞
page 31) allows users to adjust the focus optimally in the
range of the capability to automatically follow the variation in illuminance. (Note: The adjusted focal point is not necessarily
the same as the optimal focal point at the illuminance.)
• The out-of-focus level in the near-infrared light region may be higher than that in the visible light region.
Setting "C/L
←→
B/W" of "BACK-FOCUS SETUP" to "AUTO" or "PRESET" in the setup menu allows users to adjust the focus
in both the near-infrared light and visible light regions. (The variation in illuminance is not followed after focus adjustment.)
<How to use varifocal lens>
• Reset the back focus position to restore the default position before the back focus adjustment. (Hold down the right and
left buttons among the operation buttons simultaneously for 2 seconds or more, or move the cursor to "MANUAL-ADJ" of
"BACK-FOCUS SETUP" in the setup menu and hold down the right and left buttons simultaneously for 2 seconds or more
after pressing the setting button.)
