I got my D5000 a couple weeks ago. I have been using a first series 18-200 VR lens (with the red VR). It seems like all my pictures are somewhat blurry, pixelated, or just not sharp. I was looking at them compared to my old Fuji P&S pictures and the fuji ones almost look sharper. I tried to take some moon pictures two nights using a tripod with the VR on and off and they show no definition in them. Once I zoom in a moderate amount the detail disappears all together in the pictures.
Could it be a setting or can it possibly be the lens? When I get home I am going to take some test shots side by side with my 18-55 kit lens. Here is a link to my flickr page. The first half page are pictures with the D5000 and 18-200 lens.
Am I possibly expecting too much? I looked at comparable pictures that someone had taken with the same body + lens combo and they seemed 10 times sharper then mine.
