the extension isn't mentioned as required on the housing manual or the 4 inch dome sheet, just mentions it as helping improve optics.

Just to clarify, in the lens chart for the Aquatica 4" Dome Port, 18410, no where does it say "helping improve optics" The chart is pretty specific on needing the 18456 Port Extension with the Tokina 10-17 alone or the 18453 extension if the lens is used with the teleconverter. If the Extensions were taken to be a "suggestion" then would the zoom gears that are specified also a "Suggestion"?

In page 6 of the D7000 Manual, Jean states: "The Dome Port may require the use of an extension ring to optimize the optical center to both the dome and the lens..." it goes on to say "A comprehensive list of the lenses supported and their REQUIRED (Caps are Mine) extensions and/or accessories is supplied at the end of this manual

Just to follow up on this extension ring "thing", this was one of the "concepts" of moving to a housed DSLR that I had never heard of.

A while back, I was poking around at some of the other manufacturer's websites and noticed that one of the manufacturers or a dealer had a terrific "interactive" tube/focus/zoom ring" selector as part of their online ordering system. More recently, I noticed that the Australian distributor fro Aquatica uses something similar, although it isn't quite as sophisticated. Maybe Aquatica Home Office could "borrow" this from their Ozzy cousins as it is quite a bit easier to use than referring back and forth to various pdfs...

- O-Ring & Housing Flood: On the o-ring…. I think the design of the main seal in the back isn't tight enough for my liking and I'd rather the housing overlapped the o-ring rather than just pressed against it. We did a shore dive towards the end of the vacation at a spot called Windsock – it's an easy walk in entry with a little bit of sand at the very edge of the water where the waves have kicked it up. Despite walking through this fairly quickly and making sure the camera wasn't subjected to any unnecessary roughness from the oncoming waves, enough sand was able to get into the o-ring to cause a major flood. We had a short surface swim and during that time, unknown to me, the camera was slowly filling with water from the sand in the o-ring.

I recently returned from a trip to Bonaire and when I found sand around my o-ring I recalled reading this post, so I wanted to comment.

I, too, have an Aquatica housing. A lot of my diving in Bonaire was shore diving with surf entries. My camera and I spent time swimming, standing, and sometimes tumbling in shallow water with a lot of fine sand suspended in it. When I would open up my camera I found quite a lot of sand that had worked its way into the area next to the o-ring, but on the ocean side of the o-ring (not the inside half). Some of that sand appeared to wedge itself in the groove with the o-ring. And when I removed the housing back that physical act caused some of the sand to move onto the surface of the o-ring. I have to admit it certainly looked like the sand had been covering the o-ring, and it was a bit scary! However, the inside of the housing was bone-dry. I carefully cleaned the sand off and reassembled everything only to find more sand there the next time.

But the point I wanted to make is that while it sure can look like the sand was the cause of the flood, my camera stayed dry the whole trip, so I believe the original poster made an incorrect, but completely understandable, assumption.

Building upon Gina's comments. The setelling of sand oin the 'O' ring groove is not uncommon. The key here is that the ring and groove is clean when closing the back. This is particulary critical when diving in areas with fine, black volcanic sand such as Lembeh. A bright light and magnifying glass are good friends to have here.
When in doubt - pull it out and clean!
