Nice video! Do you remeber what time in the video you were using the 8mm? Is this the Pana 8mm or Oly? Also do you use WWL-1with the 12-50?
All the wide angle shots underwater are with the 8mm Olympus. I don't use the WWL. I think I may have used the 12-50 only on the frogfishes as they are a bit larger. All other smaller critters were shot with the 60mm.
