I spent 6 months researching cameras to take pictures of moving objects behind glass in water. It had to be fully digital. Allow for manual manipulation of the settings. I wanted high megapixel quality. It had to have an external flash attachment and a way to surpress the flash when I didn't want it (instead of always going by what the camera is preset for). It also had to have a real good optical zoom. Eigital zoom though helpful, does decrease photo quality.
I ended up getting a FujiFilm FinePix S7000. I am pleased with it. It has automatic, partial automatic and manual just about everything. Excellent macro and super macro. Super macro will let you take pictures of things as close as 1/4" from the lens. It has 2, 3, 4, 6, 12 normal, and 12 fine megapixel settings, so you can choose the right one for what you're taking pictures of and for.
The focus can be either automatic or manual. It also has a continuous focus mode so you can move along with your subject. Great for taking pictures of wrasses. The lens view is like a SLR lens. What you see through the lens frame is what you get in the picture. Digital lenses need to guess at what you're taking a picture of and what you see through the viewer is not really what you get in the shot. The lens isn't exchangeable like most SLR cameras, however, with the purchase of a lens attachment, you can add different lenses to it like a telephoto lens, polerizer and other filtering lenses. IT really gives you a lot of freedom in photography compared to a lot of other digital cameras and it didn't cost a thousand **** dollars either...lol. I got mine at Costco for $400 when the camera was going for $600 to $700 at the time. This was about a year ago. You can still find it elsewhere for $400. Here's a link to a description and picture of the camera on FujiFilm's website. Also a link to one of my photo albums. All have been taken using the FujiFilm FinePix S7000.
We, as a people, know so much more about outer space than we do about our own oceans. This lack of knowledge can very well spell the dangers that lay in wait for us.
The oceans surely would swallow us before a rock comes down to smite the planet of it's life.
