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.

certain illuminance.).

light region.
Setting "C/L ← → B/W" of "BACK-FOCUS SETUP" to "AUTO" or "PRESET" in the setup menu

adjustment is performed in the extended range, appropriate adjustment
