Based on a pre-production Nikon D3100
Nikon has developed a habit of making very attractive entry-level DSLRs, which are rarely the best specified but cleverly designed so that they're easy and enjoyable to shoot with. The D3000 fitted this pattern perfectly, a gentle refresh of the D60 (which was itself a slightly updated D40X), it added ease-of-use features to make it a pleasant little camera despite a specification that was beginning to look rather out-of-step with the rest of the market.
The D3000 sold well, despite its rather aged 10 megapixel sensor and lack of both live view and video. However, there's only so long that clever product design and feature integration can make up for a specification that looks dated. So with this in mind, Nikon has announced the D3100 - probably the biggest refresh of its entry-level offering since it really attacked the low end market with the original D40.
The D3100 is built around a 14.2 megapixel CMOS sensor (possibly the one seen in Sony's NEX cameras?), bringing not only live view but also Full HD video capture to Nikon's entry-level model. This not only makes it the company's second-highest pixel-count SLR (after the D3X) but also makes it the first to offer 1920x1080 movie recording. It can only record clips up to ten minutes long but it's still an impressive feature addition at this level.
The body gets a slight refresh, gaining an extra button to the left of the screen, a drive mode switch at the base of the mode dial, a sprung lever to engage live view and a direct record movie button. There are also revisions made to the feature-teaching, hand-holding 'Guide Mode' and an additional autofocus mode to allow better focusing in live view and autofocus during video shooting.
