Nikon launched the Coolpix P7XXX range in August 2010, bringing out a camera with a 10.1Mpix sensor, the P7000. Not the highest by any means but able to produce good quality results. In 2011 they updated the camera, adding a tilt mechanism to the monitor and, judging by the test results also tweaking the software. However the update in 2012 is a major overhaul: with the exception of the general look of the camera it is all new. New faster lens, new sensor: a 12.2 Mpix BSI-CMOS (back side illuminated) device, a fully articulated monitor, full HD capture compared to 720p on the previous models, faster continuous stills capture: 8 fps instead of 1.2 fps. This list goes on with improvements all along, the only thing that seems to have been dropped is an optical viewfinder. For all these improvements the Coolpix P7700 is not more expensive than the launch prices of its predecessors: in this highly competitive market the P7700 is excellent quality at a reasonable price.
In making a comparison with other cameras, it seems fairest to look at alternatives that appear to have similar specifications. Canon fills this brief with the Powershot G15 and Fujifilm with the Finepix X10. Neither of these has quite the zoom range of the Coolpix P7700 which has a range of over 7X, the Canon has a 5X zoom and the Fuji a 4X. There are numerous other candidates too, but these two seem closest. The overall DxO Mark scores for these three cameras are 46 for the G15, 50 for the X10 and 53 for the P7700. In the individual scores the Nikon wins in every measure except for low light in which it is pushed into second place by the Fuji, 191 against 245. These cameras are very similar, they are about the same size and weight, the functionality is very close too. If it were not for the different names on their casings they could be from the same stable. What makes the comparison interesting is that for all their similarity the Nikon has an indicative price nearly 20% lower than the others whilst still performing the best of the three.
Another camera that might bear looking at would be the Panasonic Lumix DMC LX7 which, like the Fuji camera, has a 4X zoom. At the time of writing this camera has not been tested by DxO Mark, but it does fit into the same general grouping and its price is still cheaper than the Coolpix. It has a sensor of 10Mpix which for photographers interested primarily in stills may be a disincentive. What it does have is higher frame rates for video and this might counterbalance the smaller sensor for those interested in motion capture. More information will be available when it has been tested by DxO Mark.
