Hi!
What about the possibility that Olympus will provide a 14mm extension ring?
1) they didn't say to do so.
2) if it's a flat port, it's still a pain in the ass. If it's a dome, it'll be ok. At least, if the usable angle of the dome is larger or equal 89° (the max. angle for the 11-22mm). I had a talk with a European sales representative of Olympus/Aqualung. They are searching for somebody to provide other ports than the ones offered by Olympus. I'm not sure if they find a cheap and practical solution.
The UK-Housing comes with a dome for all lenses on request. You may choose from flat ports for the 50mm macro, the 14-45, the 14-54 and domes for the 14-45, 14-54, 11-22, 7-14 lenses.
There'll be a possibility to have either a dedicated dome or port extensions. Dedicated domes are a bit cheaper than a shorter one plus extension but you may use it with a couple of lenses.
The dome window allows a maximum angle of 122°. You may therefore use it for all available Olympus lenses (the 7-14mm has 114° @7mm).
