Just a warning to people this currently wont work as a combination, the video/liveview knob/switch blocks it. Im just putting this up because is such a current model and theres a fair chance someone else might be considering it.
It _only_ applies to the 7d housing (dagnabit), and I couldn't see any other Ikelite pictures on their site where it might also occur and will fit on to the 40d/50d housing no probs.
To fix it you'd have to machine a new lower profile control knob or the like, and thats only a theory - I didnt try it as I had visions of insurance issues in the future, but it looked like it might be possible. Another possibility might be an increased spacer made by Nauticam, but given they dont seem to be even aware of it yet, it could be a while before one turns up and I cant see how it could really be done without adding in another leak possibility.
I dont think this is anyones fault and Peter Mooney from Scubapix has been great with all of this and offered a wealth of options to help, it just the joy of combining systems that turns up from time to time and getting to occasionally be the guinea pig.
The good news is my solution has been to get a Nauticam housing, thanks to a very understanding partner and Peter, but not everyone will have that as an option!
