Camera makers have been trying for 150 years to develop an all-in-one camera that satisfies the needs of most photographers. The Nikon Coolpix P600 comes closer to filling that order than any of the other ultra-zooms I’ve tested to date, taking into account the issues at the wide-angle end of that monster zoom.
The P600 was obviously designed for photography enthusiasts, by photography enthusiasts. Photographers who purchase the P600 will need to have realistic expectations — any camera with a 60x zoom is bound to be the result of countless mechanical, optical, electrical, and functional/operational compromises, and every one of those compromises is going to affect image quality in some way. The P600 will appeal to serious photographers who want to be able to cover a very broad zoom range of photographic genres without having to carry a heavy DSLR, a sturdy tripod, and a bag full of very expensive lenses.
Overall, the P600 does a remarkably good job of making those compromises palatable. But if tack sharp images across the full zoom range and architectural photography with absolutely straight lines are more important to you than the convenience of having a digicam with a monster zoom, then I suggest you buy an advanced user digicam with a short fast zoom, like the Canon S110.
