Is the nikon d5100 good for moving pictures?

I'm on a dance team and I want to buy a dslr camera. I don't really know alot about these types of camera's. I was looking at the nikon d5100 and it seemed to be reliable. I want a camera that takes nice sharp pictures with no blurry-ness. So will the nikon d5100 do the job or any recommendations, something great but cheap please.

here's some examples for what I'm looking for.

If you're looking to take pictures of action scenes [such as dance] I think the best advice is to get a camera with a high FPS rating [Frames per second] with minimal lag. The camera your looking at has 4 FPS, which is pretty good. Personally, I prefer Canon versus Nikon, so I would buy the Canon T3i or T4i

While the picture looks more like a Judo class than a dance recital, I get your point.

The Nikon D5100 will do the job. My daughter and a Flickr friend both have the D5100 and are getting great results. The Flickr friend shoots surfers and stops the action nicely. The kit 18-55mm lens will do you just fine to start, and you can always get a faster lens if you need it. I like my 50mm f/1.8 lens for indoor action shots.

Blurry-ness will depend a lot on you. You can either shoot in Sports mode or, better yet, learn how to use the DSLR, learning aperture, shutter speed, and ISO. You can take classes or maybe you can learn online.

For shooting video, a digital camcorder is far much better.
