Hello all, I ended up building a rig for the RX100 ii. I bought a nauticam housing and 2 Sea&Sea ys-D2 strobes, I practiced with it in manual mode a lot and then used it with the housing and strobes at night on land to get the hang of it. I set up the the camera with 2 or 3 settings I found on the web to start with and that was a big help. I took it to a local Quarry to practice and then to the Maldives for three weeks this fall. It preformed well when in auto mode. I was disappointed in close ups without a micro wet lens attached. A number of nudibranch pics turned out a bit blurry. Over all most pic turned out ok, some were over or under exposed a bit but I shot in RAW and was able to adjust them in lightroom with no problem. My biggest problem was not with the camera but with the sync cords. I bought one from Blue water photo when I bought the housing but cheaper out on the second and got it on EBay. Big mistake! It fell out over and over again. Ordered a second one from Bluewater the minute I got back to the states.
