Manual Focusing using the Focus Mark (Focus conrmation 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 viewnder’s LCD to signal
that a picture is in focus.
If is lit in the viewnder’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 dierent distances within the focus
frame (animals in cages, etc.)
• Subjects with continuous repeated patterns (building exteriors, blinds, etc.)
• Extremely backlit reective subjects (car bodies, water surfaces, etc.)
• Or when the subject is far smaller than the focus frame
