Is this play in how the  lens mount maters with the body or play in the focus
barrel and mount.?
Some play is normal.  The locking key in the lens could be small, allowing the
mount to r
"rock" slightly back n forth in the notch of the body mount.
The notch in the body mount could be worn allowing more play than usual.
I have found varying degrees of mount play, most of it is of little consequence
under actual use.
