Thanks guys. I was initially drawn to the D80 (I shoot a D70 above water) but reading reviews am not convinced with regards to the blown out highlights issues when using Matrix metering (though admittedly I normally use Center Weighted underwater on my F90 and would likely continue to do so with a digital). I know that this is relatively easily overcome but I want to reduce my workflow for each image as much as possible. I've also read a number of people who traded their D80's to 200's for this & other reasons. No disrespect to any existing D80 owners intended - for my situation, at least the price has dropped recently making the difference in total kit spend negligible. I'm also speculating that the difference in housing prices may also be insignificant.
Fair comments around the 20mm lens - it's just that as I have the lens I guessed there may be a use for it. The only lens I do need to get is the 10.5mm and it has been a difficult decision to make to either get that or the 12-24 but as I like using the 16mm underwater so much I'm sure the 10.5 will be the same.
Starbuck, a couple of follow up q's - what port do you use for the 15mm (or 16mm in my case)? Do the Inon strobes offer enough power and coverage for wideangle and especially the 10.5 lens?
I'm admitted I'm totally confused with the external TTL converters but definitely concerned around the amount of reliability/compatibility issues I'm reading on these forums. I'd much rather have cabled TTL but if that's not possible (without housing above water strobes) am assuming that STTL with the Inon maybe the best option - comments? Otherwise how well (and reliable) does the Mattias converter work and can you still dial back exposure on the strobes themselves?
