Manuals hard to understand?
You might want to go to the link below and view the Nikon Digitutor for the D7000. It is a video on the Nikon site that will give you a good over view of what the camera can do and how it operates. Each time I get a new Nikon I review the video for my new camera and recommend you check it out also, Jeff

Here is the link to the video.....
