I just got back from a trip to Barkley Sound, Vancouver Island with Rendezvous Dive Adventures and used the Laowa 10mm again. Blake at Aquatica was kind enough to ship me their prototype dome port for this specific lens, so I gave it a try too.
This is a very challenging lens to use without excellent ambient lighting. With very poor viz in the first 30 feet it made for some really dark diving, which makes the ultra-wide angle even more challenging. I am using two Kraken 18,000 lumen lights, it's tough to avoid backscatter, even with the lights angled way out because of the ultrawide angle of the lens. With good ambient lighting though, this lens is pretty cool to use!
