Nikon D5000

I want to know if anyone has used the D5000 for underwater photography? It is on sale at a store here in Japan for super cheap, please let me know soonest. Thanks

The D5000 would be fine. It is a good camera, maybe not as good as the D7000, but it will take many AFS lenses and shoot video nicely. You can't use the Tokina 10-17mm fisheye lens or other non AFS lenses, so that is a limitation. You would want the Nikon 10-24mm, and the AFS macro lenses.

I think the reason people don't use it much is that the cost of the body is not much compared to the rest of the system. The housing, ports, tray, arms, strobes and cords will cost you $3000 or more, why go cheap on the body? Pricing is changing daily, but at this time a good D5000 body costs say $500, while a D7000 is $1200. So f saving every cent is important, the D5000 will save you a bit compared to say the D7000, but considering the cost of the rest of the system, it's a small savings.

Other option is to get a D90 on sale
