fyi - I live in chicago so cold great lakes wreck diving is one place I'll definitely be using the camera but I really got interested in getting something because I'm taking a trip to Bonaire in feb 08.
I was thinking the same on the sigma 50mm f2.8 based on having read the compatibility chart on fantaseas site.
How's their dome port compared to other options. Ikelite looks better and cheaper doesn't it?
Any word on new ports/zoom rings being made for other lenses? Their selection is pretty small.
Hows a 580ex flash (which i have) in the fantasea housing compare with some of the other common flash offerings (light output, coverage, usability, etc)? How well does it work together with a INON z240 with the optical trigger? Is the inon flash often necessary?
At least fantasea didn't skip on mounting buttons for some things like the menu and delete button that s & s missed right?
Their dome is 5" is works fine out to about 12mm in my experience. I usually recommend the Sigma 15mm FE for that camera. Not the largest and that is a limitation.
There are several other ports including a 100mm macro and a semi-dome, as well as a 15mm ext ring. I set up my D80 for a Sigma 17-70 macro with a dome port and ext ring. So there's options, not as many as other manfs though. They are working on that issue, but I can't give any idea of a time frame.
The ports use a unique velcro tape/plastic cam for the zoom control, so no focus gears. Sometimes that can double for man. focus, but generally no manual focus, or it's all or nothing during the dive.
The ports are aluminum and do have a double o-ring system, pretty beefy.
The F580ex (exII now) is a nice housing and give eTTL with the camera. I would use two of them if you want a second strobe with a optical sync cord between over an Inon for a second strobe. They are powerful and accurate, but not as wide as other offerings, IMHO.
Yes, Fantasea included the Delete and Menu buttons. another very nice feature if you are cold/warm water diving is that the handles adjust in/out in width for gloves/no gloves. I've added some soft bike handle bar grips on mine for $10.
Much more specific info is available from the F400D manual.
