Please don't tell me you've turned into DPR's Richard Butler, Kunzite! :)
If you crop to an APS-C sized frame, there's no way that when only one eye was in focus, the other one suddenly becomes sharp too.
As for enlarging, this is the digital age, that metaphor doesn't work.
The sensor pixels are the same size between the K-5 and the K-1, and an output device would still be 300 ppi whether it's fed an APS-C image or a FF one. There isn't any upscaling involved in that example until you print larger than 11" by 14".

This 'equivalence' crap has to stop! :D
The aperture doesn't change. The focal length doesn't change. The exposure doesn't change. The depth of field doesn't change.
What you get is the middle fifty percent of the FF frame, that's actually what 'crop' means, a reduced field of view.
