Ha ha, Interceptor121, are you bringing your Nikon into the water? I sold my LX-7, probably get the GH4 if there is nothing decent on the market. I was seriously considering the Sony A6000, but I think I will focus more on video, hence the GH4.
Not for now.
I am quite happy with the RX100II performance underwater
This is my first proper set of still from Galapagos conditions were difficult but I think the camera did very well
