The lock feature is pretty sweet! It's a little shake close up though. At farther range it's pretty smooth, but gets very jittery close up. This is especially noticeable with the binoculars.
It also appears to be a global setting. As in if you lock something in the Observation Scope, then go to the bridge and activate the UZO, it'll auto turn to lock and follow your current target.
Here's a quick video that shows both the shakiness and the persistence of the "follow mode".
(It's pretty rough right now, but resolution should increase in a few minutes once YouTube is done working it's magic.)
