Nikon P1000 superzoom camera lets birders and astronomers go long

For camera nerds, bigger is better when it comes to sensor sizes. Sometimes, though, small sensors can be used to great effect, as Nikon's Coolpix P1000 proves. This massive bridge camera boasts an astonishing zoom range of 24 mm to 3000 mm in 35-mm lens equivalent terms. Nikon says that range is enough to fill the frame with the moon, for just one extreme example.
