A] Why are my pictures blurred?
There are several reasons why a picture may not be sharp enough. To diagnose which one is the culprit and fix the problem, you’ll need to view the shooting details when playing back the image (by pressing up/down on the multi selector) and magnify details using the playback zoom buttons.
Depth of field
If parts of the subject or scene are sharp and others are soft, it means the depth of field was too shallow Fix Choose a smaller aperture (higher f-number)
If the subject is blurred but the rest of the scene is sharp, it means they moved during the exposure Fix Choose a faster shutter speed
If the whole image shows motion blur, it means the camera moved during the exposure Fix Choose a faster shutter speed or use a tripod
If the wrong part of the image looks sharp, it means the focusing wasn’t accurate Fix Choose an AF point manually
