For those after the absolute longest lens on a compact camera, meet the Nikon Coolpix P510. At roughly the same size as Nikon's last full-size megazoom, the 36x 22.5-810mm P500, the P510 packs an "oh wow"-inducing 42x 24-1,000mm lens.
The Good
The Bad
The Bottom Line
The thing is, there are not a lot of things you can do with a lens that long on what's essentially a point-and-shoot camera. With the lens fully extended, it's very difficult to hold the P510 still and keep your subject framed, and the autofocus is very slow, so fast-moving targets are a challenge to shoot. Plus, while the image stabilization is very good, you're still going to want it on a tripod to avoid blur and using its higher ISO settings.
That said, the zoom range does give you a lot of shooting flexibility and the P510 has plenty of other positive attributes that make it worth recommending.
