<wrap note>Lens does not have optical/centering adjustments. The last element in the rear group (away from the RE) is spun into the housing, the rear zoom group is spun into its housing, and the rear element of the front zoom group is spun in. Focus does not have hard stops and instead relies on limit of travel. The zoom does have a hard stop, but it may not be utilized at one end (in my case, the wide end was stopping via the follower.)</wrap>\\
