I haven't had any success with one touch white balance.  Underwater Auto, then pulling out some magenta, seems to be the best strategy I've found too.

 

Peter's suggestion is probably the "best practice", but I'm not usually that well prepared.

 

Kalupa - do you have some samples online of the graded SLOG underwater?

Nauticam's owner Edward Lai used the camera in Taiwan, and he had lots of positive things to say about color and resolving power.  His feedback is valuable, as I don't know many people that have used more, different cameras underwater.

In Topic: Olympus 7-14 mm f2.8 will not fit in Nauticam housings

They went for the previously speculated 30 mm extension on a dome port for the Pana 8 mm fisheye.

 

Undoubtly the Nauticam 4,33 mini dome with the 30 mm mini extension should also work.

 

This does "work", but there is vignetting from the lens shades at the top and bottom of the 4:3 frame, so it won't be the recommended option.  

 

The official recommendation for Olympus 8mm f/1.8 Pro will likely be 36048 140mm Glass Dome + a new 17mm extension, but these options are undergoing ongoing testing.

The diving looks amazing, and the housing feedback here is interesting.  

 

What is the water temp?

 

A7 definitely isn't the top choice for video shooting, but it is serviceable.  A7S is outstanding.

Sony has a 16-35 f/4 lens in the FE (full frame E-) mount that has been available for a few months, and works well in the 180mm glass dome.  This is actually one of the best wide rectilinear zooms I've used, and I am really impressed by the performance in the relatively small dome.  FF systems from Canon or Nikon typically require something much bigger...

 

I really like Sony's strategy with the "purpose" built models that use the same lenses, and go in the same housing.  A7, A7R, and A7S all use one housing, A7 II and (fingers crossed) A7R II should use another.  This allows me to have high resolution (A7R) and highly sensitive (A7S) bodies that I can use interchangeably, as needed, in one housing.  These have been my primary two travel cameras, using A7S for video and at night, and it has made flash obsolete.


In Topic: Nauticam Safety Lock buttons..........stuck

This isn't unheard of, especially in mucky spots.   A good flush under running water from a hose helps. 

 

These parts are constantly being improved, with ongoing revisions to make these buttons more resistant to sticking.  The latest revision is a significant improvement, and is installed by service centers at no charge under warranty, or as a part of annual overhauls.
