Adjusting the focus
When it is difficult to get the proper focus in autofocus mode, you can
adjust the focus manually.
Notes
• When the Wide AF area is used, the center area is used for focusing; when the Zone
AF area is used, a typical area of the selected area is used; and when the Local AF
area is used, an area that is selected with the control button is used.
• When using a tele converter (sold separately), etc., rotation of the focusing ring may
not be smooth.
• The correct focus in the viewfinder is not achieved if the diopter is not adjusted
properly in viewfinder mode (page 29).
• Make sure to set the focus mode switch to MF for manual focus. Do not rotate the
focusing ring without setting to MF. Rotating the focusing ring forcibly without
switching to MF may damage the focusing ring.
