To perform fine adjustment of the back focus after automatic back focus adjustment, use
the right or left button. (No operation for 10 seconds or more closes the setup menu.)
Note:
• When an auto iris lens is used to record a 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.
• For adjustment according to "How to adjust the back focus", the focus can automatically be
adjusted under the optimal follow-up conditions even though the illuminance changes (Note:
The adjusted focal point is not necessarily the same as the optimal focal point at a certain illu-
minance.).
• The out-of-focus level in the near-infrared light region may be higher than that in the visible light
region.

the setup instructions (PDF) 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.).
• When a non-Panasonic lens that has an extended range for lens focusing is used, adjust the
back focus after setting the focus to a position at a short distance from the FAR end. If adjust-
ment is performed in the extended range, appropriate adjustment.
