Hi,

What do you guys think of below? Note that these are taken from lenstip.com and are actually meant to show longitudinal chromatic aberration.

I think that the Nikkor's rendition of background is particularly interesting.

Many comments on the nominal fuzziness, but not so much on the OOF blur. Both 10s on the scale (foreground and background) look less blurred with the 58mm than with the other two.

Well the conversation here once again turned to "which lens is sharpest"...

What you noted was one of the design goals of the 58.

"In consideration of this idea, we suppress resolution at a short distance within an appropriate level, and adjust the balance among lens aberrations moderately to prevent a drastic change of bokeh."

And as others have noted, and again is by design, at shorter distances the lens is softer at the focus plane but becomes sharper as the distance increases. It also has a softer transition from in focus to out of focus than some other lenses. This is the give and take with optical design they have to work with. They chose one path, Sigma chose another.
