If you would have used a camera then you would have seen the focal blur.

I rendered the table edge area again with

     aperture 5
     blur_samples 100
     confidence 0.9
     variance 0.0

and didn't use Photoshop to blur the edge.

There was a sharp edge when I used variance 1/128^2 as suggested by Warp.
