Hello! I'm new to the forum, however not new to photography. I recently just bought myself the Nikon D3100. Last night we had a full moon, so I went out to try to take shots with my Nikon with the lens AF-S Nikkor 55-200mm 1:4-5.6G ED VR. The shoots I was getting were very blurry (on a tripod, and hand held at one point). I honestly don't remember which setting I was in, but I did change the ISO setting... At one point I thought I had a good shot but it was still blurry but not as bad as a big bright white dot. I tried it in auto, guide, and manual still didn't get a clear shot of the moon, and I know the moon was focus when I looked through the fiewfinder. The moon last night was beautiful, just wish I had the shots to prove it. I am new to the DSLR world, which btw I really love my camera, it's a big step up from Fuji FinePix S2000hd. And I find I may never go back to that camera. I like to do a lot of macro work, and last night I really wanted to take the shot of the moon and at one point I just got discusted with the fact I couldn't get it the way I wanted it. I know it's not the camera's fault. If anyone can help I really would be grateful. If someone needs my shots to see what I did wrong, I can post them but it'll have to wait until Friday.
