Engadget recently reviewed a new Sea & Sea camera, the 860G model which will be available soon.  The new camera is a 6 megapixel, 3x optical zoom camera.  Sea & Sea has 4 other models (click on this site and then go to products) which can be used underwater (150 ft. maxium depth) and on land.  Sealife is another company which now has a underwater camera which can be used both underwater and on land, the DC500.  The biggest difference is the DC500 has the housing built around the camera.  Let us know if you use or have used a Sealife or Sea & Sea camera and what you think.  Even submit some sample photos to us at images [at] scubaology [dot] com.
