I know this lens just came out but I was curious if anyone has tried one in the water yet or plans to soon. It seems like it could potentially be a cost effective alternative to the popular Nikon 16-35mm f/4. The Nikon minimum focus distance is 0.29m, the Tamron website says this lenses minimum focus distance is 0.28m.
Has anyone figured out how much extension ring would be needed on a Nauticam housing with this lens yet? I might try to rent one soon if Borrow Lenses or Lens Rentals gets one in their fleet.
