The camera does not focus using the auto
focus (AF) setting.
Autofocus does not focus well sometimes due to reasons such as distance from the subject and
the environment in which you are photographing.
Check the solutions as follows according to the conditions or environment.
Make sure you are not too close to the subject.
The minimum distance from the subject in which you can photograph (minimum
focusing distance) is determined by the individual lens.
Photographs will not be in focus if you attempt to shoot at less than the minimum
focusing distance. Please shoot at the focus distance or farther away from the subject.
Minimum focusing distance is noted on the front or side of the lens.
Example: For SAL1855 DT 18-55mm F3.5-5.6 SAM), minimum focusing distance is
noted as "1.25m/0.82ft" in meters (m) and feet (ft).
Make sure the subject or environment do not inhibit focusing.
o Subjects with no contrast, such as blue sky or white walls
o Situations where multiple subjects are at different distances within the focus area
o Subjects with repeating patterns, such as building exteriors
o Bright or backlit subjects
o Shiny subjects, such as water surfaces, and glossy subjects
o Fast moving subjects
Focus as follows for such subjects or in situations where it is difficult to focus.
7. Compose the shot with the focus locked using a subject at the same distance
