Why are some photos blurry taken with the AZ252?

This is usually because the camera was moved when taking a photo or you or the camera were unsteady. Try using the Image Stabilization setting on the AZ252, which helps the camera automatically correct for accidental movements. 

When focusing on your subject, press the shutter button half-way down to focus. You will see a green square around your subject in the AZ252 LCD, this is your indication to continue to press the shutter button down all the way to take your photo.
