Kubrick`s Lenses

Take a look at this lengthy document:

On page 41+ it has some examples. Basically it seems you can improve sharpness for out-of-focus regions, but with other tradeoffs in image quality.

Yeah, that's what I meant. DOF is "acceptable unsharpness." So if the in-focus image isn't too sharp, then you can't tell that the OOF part is any less less sharp by comparison. It's all relative. At least up to a point.

I have noticed that comparing a Sonnar-type lens to an Elmar-type that there is a more pronounced out of focus background look on the Sonnar. I'm talking about the same focal length and aperture, and the background is out of focus with both, but the defocused objects seem more discernible on the Elmar.
