I was looking at the C-7070, but have been out of the camera scene for a while. I usually shoot with a non-strobe S-230 setup. It's very basic.
I'd like to go the route of an Ikelite houseing with a TTL strobe hooked up to the hot-shoe.
Anyone know what a good mid-range camera with that setup would be? 5060, 7070, 8080?
Personally, I think the 7070 is more practical for underwater use, the 8080 is better for land use. The 7070 zoom lens does not extend as far as the 8080 lens, but it is a very small bit wider (27mm vs 28mm eq). Because of this slightly wider lens and more compact body, for underwater the 7070 wins, in my opinion. You can buy either of them new or used still on the big auction site.
For the lowest cost TTL flash system, get the 7070 in an Oly PT-027 housing with the HeinrichsWeikamp converter. This allows you to use any TTL Nikonos compatible strobe that is fast enough (see his site for a list), even old Nikon SB105s. You save a bundle on strobes. The Oly TTL bulkhead connector is prone to corroding and freezing, then breaking off when you twist it to try to remove the connector, but the HeinrichsWeikamp converter replaces that bulkhead with a better one. This is a low total cost solution that works very, very well for macro work, but not so well for wide angle (see below). If macro is your interest, it's fine. For the converter and strobe list, see:

It has limited wide angle capability, because the OLY PT-027 housing does not have a dome port and it's wide angle port mounting is terribly fragile. See a discussion at:

Since the Splashdown article was written, INON and Athena have made superb glass domes for the PT-027. The INON solution uses the INON AD28-100 WAL, the INON dome port, and the INON AD28 adapter. The AD28 adapter is stronger than the original OLY wide angle port mount, a huge improvement. The Athena dome is available in Europe, and with it you use the INON WAL and some adapters.
For INON, see Ryan at Reef Photo and video,

Athena is harder to find, but the mikedive site offers it:

But adding a dome port etc to the PT-027 makes little sense economically, since the Ikelite housing plus dome port is of similar total cost and much more solid. That's a better wide angle solution from a reliability viewpoint. Again, Ryan at Reef Photo and video can set you up with that.
