I've been using it for half a year now. Great camera. Bought as a replacement Canon S5IS. I am very pleased with the quality. Nothing creaks. It sits perfectly in the hand. Even with my 18-105 lens. Most of all, very weak noises at high ISOs are pleasing. The swivel display is very easy to use. Fast burst shooting. There are a lot of photos you can take in a series. I didn't even try to "shoot" to the end. But 15-20 pieces can definitely. In general, I advise. They want a lot of money for the D5200. And there will be more noise at 5200 due to the larger number of megapixels. While they are selling the D5100, I advise you to take it!
