D90 for primary video?

[suddha]

I've got a dilemma. I'm starting to dabble in UW video after a couple of years shooting UW still with an Olympus P&S in a PT-033 housing. I got spoiled when I recently was able to test out a Light & Motion video housing with a Canon S10 in Bonaire. (here's my review if you're interested:
Light & Motion Bluefin Underwater Video Housing (w/Video) | Gear Patrol)

Now my dilemma is, I have a Nikon D90 and a Canon S20 videocam. No housing for either but I want to start doing hi-def video. The L&M video housing is VERY expensive ($4K +) and it seems to make more sense to get a housing for the Nikon and just take one camera on trips for topside/UW, still and video. But how's the Nikon for UW video?

Any feedback on which route I should go? Thanks in advance...

The D90 record very nice films BUT the autofocus don't work as the lifted up mirror will obstruct the autofocus sensor while recording films. This is a design flaw of many DSLR and in newer models the autofocus sensor is located in a position to allow autofocus to work while recording films. You can still use manual focus but you will need a housing with a manual focus port and this will limitate your choice of a housing.

Thanks for the reply. That is pretty much a deal breaker for me. The path I need to take it clear - get a dedicated housing for my Canon videocam.

Thanks again!
