Summary: Considering that you can get the D3100 for $250 less than Canon's Rebel T2i, the D3100 stacks up well against that top dog of the entry level. Sure, it trails the Canon a bit in resolution and focusing speed, especially in dim light. But the D3100 has even more accurate colors than the Canon and basically matches it in noise performance.
Excerpt: In the last several years, Nikon has been updating their 10MP, entry-level DSLR on an annual basis. In the past, the D40X, D60, and D3000 all share a version of the 10MP CCD sensor that was also used on the D200 and D80, but there have been some significant improvements such as the AF system.
Excerpt: Apparently, when Nikon decided to add video capture functionality to its D3000 follow-up, they weren't just kidding around. Not only have they made it the first Nikon DSLR to capture full 1080p (1920 x 1080) footage, but they also made it the "world's first" DSLR with full-time auto focus in Live View and D-Movie modes. It can even capture the 24p stuff that cinema-types crave.
Excerpt: Nikon has taken the wraps off the Nikon D3100 ($699) , introducing a substantial upgrade to the popular entry-level Nikon D3000 DSLR . With category-leading features like a 14.2 CMOS sensor, 3″ LCD display with Live View, 100-3200 ISO (expandable to 12,800), 11-point full-time auto focus, a bevy of case upgrades, and 1080p 24fps HD video with auto focus, the D3100 is virtually guaranteed to cause a bad case of gear-envy with previous gen and D90 owners longing for some...
Excerpt: This review got off to a bad start: the DX format camera arrived just before a long holiday break… without a battery and fitted with a less than ideal (for review purposes) f4.5/55-300mm lens (equivalent to 82.5-450mm on an SLR). So it just sat on the review bench for nearly two weeks, uncared for and bereft of admirers.
Summary: While the D3100 is designed to be easy to use and to actually teach the user a little bit about how to use a digital SLR camera, we feel that the interface could stand to be a little better. In particular, the scene modes on the mode dial are only indicated by their icons instead of labels, so many users won't know what they mean. We also wish the screen was a little better, as it sometimes does not reflect accurately what you have taken.
Summary: Nikon's new entry level DSLR offers nice still image quality with good high ISO performance all rolled in to a compact and light DSLR. The 18-55mm kit lens is a solid if unspectacular performer with average AF times, but generally good image quality and a very usable close focus distance. Shutter lag seems minimal despite timings that place it toward the bottom of the pile amongst entry level DSLRs.
Pros: Good image and color quality, Good high ISO noise performance, Light and compact, Kit lens offers good close up capability
Cons: Short video capture time, Fairly noticeable rolling shutter effect
