Inheriting a lot from the D90, but missing a live-view mode in this time and age could prove to be a hard nut to crack. However: "There is no doubt that the D3000 is an evolutionary, rather than revolutionary update, but the few features that have been added to the D3000 compared to the D60 are of real value, and the 11-point AF system alone makes the D3000 a bargain at its current asking price. It's a shame that the bundled 18-55mm kit lens doesn't show off the AF capabilities of the camera to a better extent, but the same is true of most kit lenses. A greater frustration - at least to anyone with a collection of older Nikon lenses - is that AF is unavailable with non AF-S optics. Fortunately, the D3000 does offer an effective (and very accurate) manual focusing rangefinder indicator in the viewfinder, but it's of little help when you're faced with a moving subject." Link
