I just started with the DC800 with external flash. I like it. But it took me a while to figure out what settings to use for the various shooting modes.
I think it takes great pictures for the price. I’m thinking about adding another external flash unit though.
Greg is correct. make sure that you have a fresh moisture muncher in the housing when you dive.
Also, if you are using the external flash... make sure that you have plenty of AA batteries to spare. The flash really eats up batteries.
