Nikon 1 J2 review: All Quiet on the Eastern FrontMonday October 29 2012 Sensor Review
In terms of color depth, the Nikon 1 J2 is in 125th place in the DxOMark rankings with 21.3 bits.
With a dynamic range score of 10.8EV, the Nikon 1 J2’s 1" CMOS sensor does not come close to the potential of certain other recent Sony sensors that reach 14EV. However, it should be noted that the 1 J2 is tied in this category with the Canon Powershot G1 X.
As for low-light sensitivity, the Nikon 1 J2 is still handicapped by its modest sensor surface size. Only Fuji expert compacts with 2/3" sensors or expert compacts with 1/1.7" sensors do less well. The J2 scored 363 ISO on our test bench, meaning that it would not be the best choice for shooting interior shots or under low-light conditions, at least in terms of RAW file potential.
