Nikon D610 review: What's new?By Kevin Carter - Friday October 18 2013 Sensor Review
With a DxOMark Sensor score of 94 points the image quality of the D610 is impressive and is the third best sensor measured using our system.
Portrait (Color Depth): 25.1 bits.
In joint fifth place overall in our Portrait scores; the D610 achieves a very high score approaching that of the Phase One P40 in our database. Although that and the P65+ aren’t the latest models from the firm, it’s an excellent result for the D610 (and the previous D600).
Dynamic Range (Landscape score): 14.4 EV
In terms of dynamic range, the D610 ranks in joint first place alongside the Nikon D800 with a DR of 14.4 EVs. Nikon occupies four of the top five positions in this category, however all the cameras listed adopt Sony-sourced sensors. Incidentally, the D610 is marginally ahead of the RX1, which is believed to adopt either the same or a very similar sensor. The scores appear to bear that out
Lowlight ISO: 2925
The Nikon D610 ranks in fifth place in the top five for low-light ISO scores in our database, but is still very close in real-world terms to the others. That’s especially true when you remove the Nikon D3s from the top spot, as it’s no longer made, and difficult to find new (if it can at all).
