The RX100II has a 28mm equivalent lens so the wet mate is not really an option. On the LX7 you can have the wet mate for 24mm and the Inon if you step zoom to 28mm. There is a potential vignetting issue using the nauticam LD mount. No issues with the M67 mount and with the fix LD adapter for the LX7.
The Inon lens is expensive but really the best option for wide angle video for the RX100 because it also has an optional hood that protects the lens and avoids flare.
For the LX7 you don't really need the extra field of view for reef scenes but maybe for wrecks is desirable. Take into account that the RX100 image stabiliser also crops the image so with the Inon you get an equivalent fov of 95 and not the 100+ you should get
I have tried also another Inon wider lens but I am not happy with the quality in the corners in comparison although the lens is wider for me optical quality is the most important thing not 10 degrees more fov that I can compensate with my fins

I'm quite happy with the Wetmate and don't see myself getting the INON at the moment. My only real issue has been as you know WB but I'm hopeful that the addition of a red filter will help in that department. Only hitch is when I turn on my lights to film quicky into dark areas (over hangs, crevices, etc). I'll have to see if I can MWB with the red filter and lights as opposed to having to remove the red filter.

When you do custom white balance do you ensure the exposure is correct?

I cant say that I did. I was normally placing my hand anywhere from 6-12 inches in front of camera trying to angle myself to avoid as much glare on my hand as possible. Sometimes I would use the backside of my hand since it seemed less reflective.

What method could I use to check exposure?

Ensure the Ev value is between -2 and +2 otherwise the balancing fails

Great video,thnx for sharing

 

[EL Pistoffo]

My exposure compensation is usually set at -2/3

What are the settings for min max ISO and what shutter speed are you using?

 

[EL Pistoffo]

I've got max ISO set at 400, haven't noticed a min ISO setting. Shutter is 1/125. I basically went with the recommend settings from your blog.

So that should be fine. Do you have issues with white balancing at all depths or more at surface?
I never had a filter on the LX7 and the adjustments with iMovie are not significant so am not sure what's going on with your set up. I read on backscatter they had issues with the custom white balance but then I have the same with the sony so did not give it any importance.
Next step is to buy a whibal slate
