>>4478115D700 and a housing with some 14mm Sigma EX lens that likes to backfocus I did my best to clean them up. 
I have a way better setup now, D700 and D800 both with housings and Sigma 28/1.8 EX and I dialed the focus in perfect. The 14 doesn't backfocus on the D800 for some reason but the edges are really soft in the dome housing I have so as long as I don't put anything super wide on it the corners and edges look good. Underwater is weird, lenses do all kinds of weird shit with light in the water. I've been looking for a 20 that fits in my housings but anything not shitty won't clear the entrance to the port.
