I think it was to do with how close is the camera to the subject... as you can see in pic #3 the background is perfectly clear... so maybe you want to be too close to the subject it becomes blurry...

not sure with your camera but I think you have to be at least certain cms (10 I think) away to get in focus closeups...(camera wise, and you can always zoom in from there)... other cameras allow you to be 0mm away from subject but thats super macro and only in certain models
