I just looked up the photozone test report.  This is one paragraph from their "VERDICT" of the lens.    http://www.photozone...-tokina162828ff

 

"Unfortunately there may be a hair spoiling the (optical) soup here - quality control. As mentioned we purchased three lens samples for testing, two in Nikon and on in Canon mount, and all three showed some centering issues. The initial Nikon variant was so poor that we had to cancel the testing procedure. The second sample, used for this review, was better, but still suffered from slight decentering at the long end."

Hello Alexis,

I've bought several D800's but don't have a housing yet.  Shot with the D700 underwater on my most recent trip - Bali and South Australia.  One of the reasons I may switch to the D800 for underwater use is to cut down on the gear I would have travel with if I continue to shoot underwater with the D700 and topside with the D800.  The two cameras use different batteries, which means different battery chargers. And back-up's for those chargers and back-up camera bodies of each type.  I also prefer shooting with only one kind of camera body so that when I reach for a particular control button on the camera it is always the same place.

You should also keep in mind that how much difference you would see between the D700 and D800 depends a lot on what you want to do with the pictures.  The higher dynamic range of the D800 will be most apparent and advantageous when shooting subjects with high contrast, such as having the sun in the picture.  The higher resolution is likely to be visible only if you make very large prints of the full frame or make fairly large prints from a small portion of the whole image area. The theoretical maximum resolution increase, 1.67x, will only be realized if you shoot with top quality lenses at their optimum apertures, which in many cases may not give you the depth-of-field you want or need for the picture.  

If you already own a D700, but not a D800, you will probably be able to save a very large amount of money on your underwater kit by buying a used housing for your D700 vs having to buy a new housing and a D800.
