Overall a fun and very rewarding experience. We were luck to have over a dozen mantas feeding around us for about an hour.
I used the Tokina 10-17 for these and generally used other lights to focus to avoid all the "stuff" attracted to the lights from gathering in front of my dome. because the D200 isn't too good at high ISO, I tried to keep it below ISO 200.
