Re: 960 serial from B&H

To tell you the truth this issue has nothing to do with batches.  You WILL randomly get lenses with or without the ticking issue.  I've done 4 exchanges with B&H and here were my results:

1. (did not recall the serial) this had bubbles on the front element

2. 03 serial - Faint ticking sound that seldom goes away but comes back

3. 02 serial - Faint ticking sound but loud squeaking sound when you rotate the zoom barrel

3. 06 serial - Loud ticking sound

4. 06 serial - No ticking sound, squeaking sound, or bubbles on the front element (I kept this one)

There are others that have reported no ticking sounds on 02 or 03 serials so I think I can conclude its all random if you get a "ticking" lens.
