Furthermore in the [url=http://www.dxomark.com/index.php/Publications/DxOMark-Reviews/With-new-STM-technology-does-Canon-s-updated-18-135mm-still-deliver/Comparisons]review[/url] of Canon EF-S 18-135mm f3.5-f5.6 IS STM lens
In comparison section:
Tested on the flagship APS-C DSLRs from Canon and Nikon, the 7D and D7000, these two Super Zooms achieve remarkably similar results. Overall we can say they’re the same optically although the Nikon version hits a DxOMark Score of 13 just nudging out the Canon with 12.
The screenshot shows us not D7000 but D300 with the score 10 not 13 as mentioned.
