Just to double check... This is a alu meikon housing for rx100 mk 4?
Nope, 40m/plastic, as he stated before.
BTW I am having 2nd thoughts about the Meikon housings:
#1: The Al would be interesting for me, however shipped, all taxes payed It would cost me above 800$, whereas I can get a Nauticam piece for 995 in the "local" (within the country, no overseas servicing, taxes etc...) store. Not a huge difference to risk warranty/service/parts issue. Also, this <200$ difference might come back once reselling the kit, because Nauticam is better known and I guess easier to sell.
#2: More important: The rear window concept gives me some worry: screws holding it against the water pressure:
This adds a possibility for a leak.
I think I'll rather decide between the Nauticam and the Fantasea housing.
