The only thing I can think of

The only thing I can think of is the contacts between the body and lens. Maybe they are a little dirty.

OR maybe a little play has begun between the body and lens mount? Does it jitter if you hold the camera vertically?

"Moving parts in rubbing contact require lubrication to avoid excessive wear. Honorifics
and formal politeness provide lubrication where people rub together.
Often the very young, the untraveled, the naive, the unsophisticated deplore these
formalities as "empty," "meaningless," or "dishonest," and scorn to use them.
No matter how pure their motives, they thereby throw sand into machinery that does not
work too well at best."
--Robert Heinlein in "The Notebooks of Lazarus Long"
