Manual Focusing using the Focus Mark (Focus confirmation
method)
Half-press the shutter release button and turn the lens focusing ring to
focus on the subject. The focus mark is illuminated in the viewfinder’s
LCD to signal that a picture is in focus.
If

is lit in the viewfinder’s LCD, the camera is focused on a point
behind the object.
If

is lit, the camera is focused on a point in front of the object.
- Use the focus mark when taking photos in manual focus mode or
when using the M645 manual lens.
- If you adjust focus using the focus mark with an M645 lens, make
sure to open the aperture. You can use this function with the lens set
to f/5.6 or higher.
When Auto Focus Fails
The auto focus function requires contrast in the subject. Auto focusing
may fail to achieve focus with certain subjects described below. In such
cases, either switch to the manual focus mode (and focus manually) or
focus on a more contrast appropriate object at the same distance as
the object you want to photograph, lock the focus using the focus lock
button on the front of the camera body, then take a picture.
• Low-contrast subject (blue skies, white walls and other objects)
• Two or more objects overlapping at different distances within the focus
frame (animals in cages, etc.)
• Subjects with continuous repeated patterns (building exteriors, blinds, etc.)
• Extremely backlit reflective subjects (car bodies, water surfaces, etc.)
• Or when the subject is far smaller than the focus frame
