The Nikon D3100, when launched in 2010, had a rather awkward position in the dSLR market, with its price highly similar to the D5000 at around the time of launch. The Nikon D5000 is a better dSLR in terms of specifications and performance, and the D3000 is very similar to the D3100 yet is cheaper, thus making the D3100 a rather unattractive choice among the 2 dSLRs.
The body of the D3100 is both lower in weight and size statistics as compared to its predecessor, the cheaper D3000, and though not lower by a huge margin, it is still one of the lightest dSLRs in its class, with a body weight of 17.7 ounces. As for choices of lenses other than the standard 18-55mm VR kit lens, the Nikon professional-grade 28-300mm lens is not balanced in terms of weight as it is too heavy when used with the D3100′s light body. A good budget lens choice would be the 35mm lens, which is older, but still offers great value.
Overall, the Nikon D3100 can be a good choice of dSLR camera for most average DSLR consumers, though it does not really offer much more upgrades over the original D3000, and therefore offers less value.
