That too is adjustable. You can change the sensitivity to sudden
changes in focus distance. The tradeoff is, of course, a possible
lack of responsiveness.

So if you program in a lack of responsiveness, a possible result is a
lack of responsiveness?

You don't read so well, do you? Do you really think that
"sensitivity" is synonymous with "responsiveness"?
