Nikon updates its entry-level dSLR with the addition of video capture, new processing algorithms, and the de rigeur bump in resolution. The D3100 adds HD video capture with continuous autofocus. Continuous AF is unusual in dSLRs, but for good reason; the focusing mechanisms in the lenses are generally too noisy and an unwelcome addition to your soundtrack. This remains true for Nikon's solution, and without a mic input, you really have no way around it. Consider it a tradeoff. The camera does have a direct-access button for movie mode rather than shunting it off to the mode dial.
Here are some basic comparisons with Nikon's other current entry-level models (tables updated with more specs):

In 2009, Nikon released the Coolpix S1000pj, a compact camera that had one very notable feature: a built-in projector for on-the-spot viewing of photos and videos. It was otherwise a fairly standard point-and-shoot, and since you couldn't beam content other than what was taken with the camera, it definitely fell under "niche product"--especially at $430. It was a solid idea, though, so it's nice to see a second generation on its way in the form of the S1100pj.
This time around the 14-megapixel camera is fuller featured, but most importantly you can connect it to … Read more
As I mentioned back at the end of June, camera manufacturers are beginning to announce models for the second half of 2010. Sony, Fujifilm, Panasonic, and Samsung have made their announcements, three of them doing so early Wednesday morning.
Sony and Panasonic are launching mostly high-end models as well as a couple updates to older, popular models. Samsung refreshed its flagship DualView cameras and introduced a 7x zoom ultracompact for $180. And Fujifilm announced replacements to three models that were barely six months old as well as a significant update to its groundbreaking F200EXR.
Here are links to all the … Read more
