Thanks a lot for posting your question.
The DxOMark score for the 18-105 (10) is a bit too low to show it off in the ranking.
Another important consideration is that these reviews are not updated when we publish new results. If you need to access a specific ranking for one camera and check every available results, you can then check the ranking page and then use the filter tools to match your specific needs.
The DxOMark score for the 18-105 is 16, not 10.
As such, it would beat the last lens in your "Best Standard zoom models for the D7100" list. It would also tie with the second and third lens from the bottom.
Maybe you meant to say that the 18-105 doesn't qualify as a standard zoom because it's too long (at 105mm)?
If so, then it should definitely be in your "Best Zoom models for the D7100" list, where it would place in the middle of that list.
But then you could say that list is for long zooms (even though the title missed to specify that fact) and the 18-105 doesn't qualify because it's too short (at 18mm).
