I'm in a dilemma. The Panasonic LX100 is 24-70mm with Power OIS. It seems comparable to the GH4 with the Lumix G X Vario PZ 14-42mm, which also has Power OIS. The LX100 has faster Leica lens, and half the price of the GH4.
I'm concern about if there would be any housing for the LX100 because the hot shoes flash for the LX100 is awkward, and the biggest problem is the LX100 has very long lens barrel, so making a housing for it might not be possible.
Anyway, I'm weighting out the price of going with the GH4 solution since it has better housing support like tripod ready, angled handle, vacuum leak test ready etc. If I were to get the 14-42mm lens for the GH4, does that mean I have to get the Nauticam P1442X-pz gear ($220) and the Nauticam Macro Port 35 ($290), so essentially additional cost of $510 just to use the PZ 14-42mm lens for the GH4?
Sorry I never use an interchangeable lens system under water so I don't know what gear is needed for what port, or if some lens even need gear if it has power zoom.
