I got a Sigma 24mm macro before my Komodo trip to try my hands at CFWA shots. The lens works quite well. In my pool test, I was able to focus all the way to the surface of the 8" Aquatica dome. I did the test at Lembeh resort of all places. The people watching me go into the pool with a dome port on my housing must have thought I've OD on Nitrogen. I'm not sure the staff there has ever seen a dome port.
Here are a couple CFWA shots from the trip
and a couple not so CFWA
The biggest barrier to getting closer is getting strobe light to the front of the big 8" dome. I'll have to find a way to get a smaller dome for the housing.
