diver dave 1,
I do like the quality of the Subsee macro lenses.
Downside: the adapter I bought for my Light & Motion housing has proved to be fragile. It cracked in half the first time I used it; thankfully my little lanyard saved it from the depths. I suspect the printing process that apparently was used to make the holder resulted in a fairly weak piece of plastic. If there's a way to get or make a stronger holder, I'd suggest doing so.
