My 3-4 years searches proved me there were no bread & butter midrange lens available for UW photography, 10-17 is the closest you can have but it's always a trade off. (although some say the 17-70 Sigma macro can be a challenger for all around shots).If i owned a decent mid range lens I would have used it on some of the dives
I'm using the Canon 17-40L as a mid range lens (I am on full frame) but each time I regret not fitting my 15 fisheye, moreover on the macro aspects, it's completely useless.
