I'm facing some problems with my new D7000. When I tried taking picture without any tripod, my pictures will come out blur even though there's sufficient lights. Why is this so? I've tried adjusting the ISO, i check the VR on the lens and it's on, tried to choose a lower Fstop and faster shutter speed but it's still blur. Why is this so? I've no problem with my old semi pro camera. Please help!!!
