Some lenses, because of a design that includes uncorrected spherical aberration, shift their plane of focus backwards as the aperture is narrowed. This is most apparent at close focusing distances and mid-to-wide apertures, but is not a defect and should not be subject to 'sample variation', yet reputable reviewers will either disagree about its presence or not test for it at all.
Which design features or lens characteristics are most likely to indicate a lens that will exhibit focus shift from un/under-corrected spherical aberration? Which contemporary lenses are known, either through direct experience or reputational consensus, to show this characteristic?
For example, from direct experience I know the Zeiss ZM C-Sonnar 1,5/50 does this, and the Canon EF 50/1.2L also has a reputation for having mild focus shift. This previous question touches on a potential cause of this behaviour with Zeiss primes for SLRs, but doesn't delve into details: Focus shift when stopping down on Zeiss Primes?
