This is a snapshot of Startrek The Next Generation, Season 6, Episode 26.
It appears to have two planes of focus, one centred on the right eye of the man in the foreground, and one on the right side of the chest of the man in the background. Two cameras with superimposing? Or some effect put in afterwards?

Possibly a post-processing effect, but another option might be that a
perspective correcting lens was used to apply some swing to the plane of
focus. Looks very much like there's a single plane of focus from Data's
right eye (our left) through the Borg, and on to the wall in the
background, which is very much an effect these lenses can achieve.

Not sure whether that's a physical option for the cameras used for
ST:TNG though...

Yes it does look that way, it sounds interesting, how can a lens do such a thing? And yes I did try google and only got unrelated results.
