Hi, I have a Dimage

as you already know the shutter button has two parts or clicks to it. the first click will allow the lens to autofocus and automatically select the right exposure, and/or calculate shutter time for the picture. when you see the hand signal, it means that the camera calculated that the shutter will stay open longer then usual to take the picture. so if you move while you take the picture it my come out blurry. all that happends during the first click, which means that your shutter button isn't making contact with the second click. it should be an easy fix at any camera shop. if its still under warranty the manufacturer should have no problem fixing that.
