With the standard AF-S Nikkor 18-55mm F3.5-5.6 VR kit zoom, the focus speed is perfectly acceptable, but not spectacular (you really need to use a better lens for the true benefits of the D3100's sophisticated AF system to become apparent).

The Nikon D3100 lets you dial in shutter speeds of up to 30 seconds and has a Bulb mode as well for exposure times of practically any length, which is very good news if you are seriously interested in night photography.

Remarkably, at ISO3200 only the sharpest pair of eyes would notice any difference between this and the previous two ISO settings.

Even so, the LCD looks fairly accurate in terms of brightness, contrast and colour balance, and that's what is most important.

In addition to a composite, a HDMI out, and a USB connector, the D3100 has a connector for Nikon's proprietary GPS module.
