Congratulations Sinetwo for your purchase.
Have you bought a new stay too? The Nauticam housing requires two screws, I don't know if it will work well if you use only one? You may consider the RECSEA ADT-1S tray adapter. It is really well built. Building your own adapter may also be an option if your good working with metal.
Not sure what Stay is, but I've ordered 2 1/4" mount screws to go into the housing and through the i-Das tray system. This should be sufficient.
I also considered the Nauticam housing but I finally selected the RECSEA for it's big front wheel control and the back wheel that works exactly like the RX100MkII's. One other thing was that I wasn't 100% sure that using the M67 with a 28AD adapter would cause some vigneting with my UWL-100 28AD and RECSEA had a 28AD adapter direct for the housing. Unfortunately this adapter has a small screw that impair a bit using the front wheel. So I decided to buy a cheap M67-28AD adapter to see if the vigneting was acceptable and in fact there was none! So the only problem I see right now with this housing is the dial mode control but it may eventually works fine underwater with the pressure, anyway as I said I will use the MR mode option that will work fine by setting the MENU START option behavior to Previous.
From what I've seen, you've got control over both the front and back wheels on the Naughtycam. This is imperative for Macro with the RX100ii because of focus peaking in the display with static subjects. Without fine control over the front dial for super macro, you rely on 1) focus luck and/or 2) focus light.
What were your main complains about the Meikon housing?
Main complaints about the Meikon housing can be seen on a separate thread: http://wetpixel.com/...=54929&p=360919
In summary they were:
* shutter button doesn't line up properly (manual horrendous cardboard fix)
* flash diffuser is too far behind the dome, so you get about 1/4 of the image illuminated (top left) and 3/4 dark, so absolutely no use at all, you HAVE to use an external strobe.
* when using an external strobe, see through casing lets light through, so this interferes with your images, particularly macro
* missing a dial for the 'round the lens' adjustment control, which is annoying as you have a bit less control with ISO/APT/SHUT depending on how you've set your camera up.
How did you like working with the RX100MkII underwater? I haven't tried mine yet underwater and I wonder how I will manage to work in manual mode with the flash not being manual I still have some experimentation to do.
If you've got the Recsea, why would you use your Meikon, out of curiosity? The RX100ii is good underwater, but you must practice with it on land., ideally in a darkish room to simulate dark environments, focusing flash effect, focus etc. I shoot strictly manual, so for me, I need to have good access to all settings such as Shutter, Ap, Iso, etc. You can configure the RX100ii to do what you want on the various buttons, but you can't assign ANYTHING to ANY button, which is why Meikon's lack of a front dial is severely annoying. You can switch to aperture or shutter and then use the back buttons to swtich it, but in the heat of the moment, you really don't have time to be playing around.
Overall the Meikon kit was good for a beginner, but it's so difficult to do half presses, and sometimes the controls get stuck and overall it's just a bad experience when you have 10 seconds to take a picture of that elusive giant frogfish before a really annoying dive master creeps up on you and takes your spot. Yes, this happened, and no, I didn't get it. That frogfish was the size of a medium ball, and had I had a naughtycam, i'd have that shot
