After sometime producing not so attractive housings (big, heavy), Sea&Sea is coming back to the market strongly by producing nice and compact housings for the Nikons D200 and D50 and the Canon 5D. Their latest new product is a glass dome port:

Their previous fisheye dome port was made of acrylic. These are the advantages of this new port (according to Sea&Sea):
* Greatly reduces peripheral aberration (distortion) so images are clear from corner to corner.
* Efficient light transmission sharpens images.
* Greatly reduces flare when shooting into light.
* Made of glass so it sheds water droplets, excellent for clear over/under shots (half above water, half below).
* Aged deterioration more resistant than an acrylic dome port.
In addition, a Sea&Sea housing for the D80 is in the works:
