Summary: I own a Nikon D300 and I love that camera. It's a work horse, but it's heavy. I was looking for a camera that I could use as more of an every day type of camera. You know, something to grab to take a few shots without a lot of fuss, weight and fooling with settings. In other words, a fun, easy to use camera. I had purchased one of the Micro Four Thirds cameras because it was light and small, but I found the quality lacking when compared to APS-C cameras.
Summary: Upgraded from Nikon D3100 and I'm satisfied with extra I paid for Nikon D5100. Flip LCD screen is really useful in hard-to-access angles and self portraits. ISO performance compared to D3100 is better and it has more shooting options in video mode. AE bracketing is useful for photography novices like me. Although weights more than D3100, doesn't feel it heavier. Easier to handle because of the small size. I love the camera so far.
Excerpt: I purchased two d5100 form cameta within 2 months. Unfortunately the first one was stolen from my apartment. I decided to buy another one since it is till best dslr value for your money right now. This time I purchased body only since i didn't care for the kit lens. Instead I decided on prime lens 50mm 1.8g. Picture quality with this setup is amazing. Eventually I would like to upgrade to d7000, but for now I'm happy. Great service from cameta. Thank YOU!
Pros: Easy To Use, Fast / Accurate Auto-Focus, Fast Shutter Speed, Good Image Quality, High ISO Performance
Summary: This was my first time shopping around for a nice entry level DSLR camera. I have had a 7 year old point and shoot camera. I was deciding to go with the D3200 but a photography hobbyist friend mentioned and recommended me this camera over the D3200. The price was a 100 bucks less but was only for the body. I purchased a Sigma 18-200 lens and love my new camera. Cant go wrong.
Summary: I was impressed when I used this camera for nature shots. It was very responsive and accurate. The built in flash was powerful enough to provide good fill flash and recycled quickly. At this price range there is not much to be disappointed with.
Pros: Photo quality is very good, Relatively low noise at high ISO's, Light weight yet very solid camera in the hands, Well placed controls, Accurate auto focusing
Cons: No vertical grip available from Nikon, No built in focusing motor
Summary: I purchased the D5100 bundle with a 18-55mm and a 55-300mm lenses in June 2012 on Amazon from a company called Cameta Camera for $1020. I have taken about 3500 pictures using mostly the 18-55mm lens 80% of time during last few months. The pictures were great. However, during my last trip to the Mammoth Cave, the 18-55mm lens stopped zooming, i.e. the lens got stuck and can only move between 24 and 35mm.
Summary: Great camera! Still learning the functions - this is not a point and shoot camera; the auto functions work well and take great pictures, but I am sure we will get much more out of it as we learn how to use it...
Summary: I have had the Nikon D5100 for 1 month now, I have never owned a DSLR camera before this one (only the 8 MP camera on my smartphone), and I was blown away with the quality and ease of use that you get from this camera. I read over the manual several times before using all of the features that are baked into it, and now I have a excellent grasp on how to manipulate every aspect of the D5100.
