I think I know what you are talking about now...
It must have been corrected.
The caption for that video:
A hybrid insect-human camera lens
This footage was shot with a tiny prototype lens being developed at Ohio State University. It combines features of insect eye lenses, such as their wide angle of view, with those of a human eye, such as the ability to shift the focus. Here, the lens focuses on letters positioned at various distances to demonstrate depth of field.
And if I'm guessing correctly, the word "shift" was spelled out as "s**t" .
Did I guess correctly?
Let me know.
