Over the past couple of years I've been using a Canon T2i and a Pro-Optic 8mm manual fisheye lens for video. I like the wide angle of view (around 170 degrees) at a decent price ($250 or so) of the 8mm, but you can't get footage of smaller things on the same dive unless you bring a second camera down with a longer lens. I just bought the Canon 10-18mm lens which is surprisingly-priced ($300-350) considering it's a "name-brand" lens. I bought it so I can have a wide-angle lens on my Canon SL1 in an Ikelite housing. The SL1 housing only has one dome port available that doesn't accommodate fisheye lenses without vignetting. The 10-18mm is equivalent to a 16mm (full-frame) at it's 10mm end. I missed the wide view of my 8mm fisheye on this dive, but being able to get semi-wide and close-up footage of fish-sized subjects with a single camera was nice. About half the footage in this video was taken at the 10mm end and the rest at 18mm. The lighting was from 2 homemade 50W LED lights. Visibility was around 20'. There were lots of particles in the water and the light levels were much lower than the tropics.
