I thought the Sigma 16mm f1.4 would have been a good option to given its wide angle and lots of light via f1.4? I know guys shooting rx100s with no zoom underwater and thats 28mm.

So what is the problem with wide angle?

Several:

1. small subjects (of which there are lots)

2. forced to deal with ambient lighting most of the time

3. corners, especially with flat ports.  (IQ)

4. corners again, except in relation to the size of dome ports you have to carry.

5. less than crystal clear water

Macro tends to have none of those issues, or to a much smaller degree.

Also, an F1.4 wide angle lens would not do you much good underwater as you typically stop down a lot to try to have decent corner and edge quality.  F8 is common starting point for my wide angle, and many stop down a few more f stops.   If exposing for ambient, you can see why ISO climbs rapidly as you descend.
