Now for the photos. the focus algorithim on the camera doesn't seem to be working. The center of the photo is out of focus whereas other parts of the image is in focus. i.e., that photo of the boy falling into the water, his sock is in focus but the center of the photo isn't.
Check the settings on the camera's focus, is it set to center focus? For close up photo like models, the center of the image should be in focus. It looks like the multi-point focus is using other items in the frame to focus on. Look at page 73 of your manual on how to turn off the Artificial Intelligence Auto Focus. This way the autofocus frame in the middle of the image is used to focus.
Let me know if this helps.
