What are you talking about? Of course I didn't add NR or did any " enhancing". I didn't even resharpen after scaling.  And if I had upscaled the A57 the relative difference would have been similar.

When you pan around, one can easily cherry pick bits where the A57 looks better as well.

Only the far left of the A58 shows a focus or lens (curvature ?) issue with a sudden drop off in sharpness. The rest is consistent with the crops posted.
