Good point. I've never (in surfing BSK's website) been able to figure out their port situation, period.
What is available? Is their port compatible with 3rd parties of any kind? How about zoom gearing? etc. etc.
Plus does their housing allow raising the internal flash for fiberoptic coupling? I see the images you linked indicate some sort of hotshoe mount - is their included TTL electronics or is the for manual triggering only?
At my level of photography (poor) and frequency of diving (too rare), straying away from Ikelite just doesn't make sense. But then I really really like the A77 (it would fix the few flaws I see in my A55, and add a whole lot of useful features like focus peaking) and Ike ain't housing it....
