Comparing the D7100 and K-3 side by side the D7100 appears to have the upper hand.

Really? can you even tell which is which... the disadvantage to the Nikon is, it can't use my DA*60-250. I would write that difference of as negligible, certainly not a reason to choose one camera over the other. That's about half the difference there is between a K-5 and a K-5 IIs.

I would say that the D7100 is the one to the right.

I see the k-3 is sharper. The D7100 has purple edges that make it look sharper, but I attribute that to the lens (even though I think they use the same lens - Sigma 70 macro). Humorously the edges and corners are sharper on the k-3 image, so that's gotta be the lens sample variation.

On the left image you can see individual lines at 30, on the right you can´t.

These test results fall well within the parameters of lens sample variation. Decide which camera you might like on other issues. That would be my advice.
