WA lens suggestions for photographing whale sharks

I've been planning two trips this summer, one to see Mantas in Kona and another to see Whale Sharks in Bahia de los Angeles, which has prompted me to buy a WA lens. I have a canon A720 with Ikelite housing. Does anyone have any suggestions for a wet WA lens that's wide enough to photograph whale sharks and that has 67 mm threads (or a converter)?

Edit: I meant to mention that I've been looking at the Inon 100WAL, which has 100 degree view angle. Is that enough to shoot whale sharks, or will I need the dome converter (allows 130 degree view angle)? Does anyone have any reviews or critiques of this lens?

Thanks!

I'd get the dome converter for two reasons:

1. Whale sharks are BIG! Even the little 15 footer I was fortunate to swim with takes all the lens you've got, and he wanted to be friendly, so he was right on top of my lens. I got an eye, a mouth and the front half of a body.

2. You'll be snorkeling and shooting at the surface. The dome will let you do over/unders.

The dome converter on the 100WAL Type II is amazing and highly recommended and should be for the combined costs. Yes, it is much wider than with the 100WAL alone.

The UWL-100 and dome is an excellent lens combination and gives you 130 degrees angle of view. It is possible to shoot over / unders however the water line between the port and rear element is annoying. If I plan o/u shots I use a thick rubber band to block the drain holes and retain the water in the 'wet space'. The other lens you should consider is the UWL-165 M67.

What is a UWL-165 M67? I see a UCL-165 M67 macro lens but no such wide angle lens. The 165AD Fisheye is a bayonet mount and would require a custom adapter such as I made to adapt to a 67mm thread.
