More excellent advice. I've experimented a little more with the settings the other posters have mentioned and have even gotten better images. But, when I dialed to 3200 ISO I started getting a little grainier than I wanted, but when I wasn't zoomed in on the image when viewing on the computer, I didn't really notice that much. The pictures were even brighter and more clear at 1/250th shutter. But, at 1/500 or more I started getting underexposed (simply not enough lighting). I did try using flash (not a speedlight) on my camera and got some decent shots, but they were not as good as without. This thread has really helped me further my knowledge of my D5000. One additional question,I got another 55-200 non-VR lens. I'm thinking it will be ok for this instance (indoor tennis shooting) as well so long as i'm using a faster shutter? Am I on the right track with that thought process? Thanks for any further advice!
