I recently bought a Nikon P7000 from Amazon for 200ish Dollars. The one thing that bothers me is the zoom lens control occasionally becomes unresponsive and requires reset by powering off and powering on. This this normal? If not, I'm going to exchange the device. If it is, then I'm going exchange it. Can any p7000 owners help me? Thank you for taking the time to answer my question. -CM
