They do exist. While I no experience with the following, it may serve your needs:
http://www.bobatkins.com/photography/eosfaq/manual_focus_EOS.html (You can Google Canon lens adapter for more entries if needed.) Since the lens must be stopped down, I would think you might only consider wides for UW use and attach a Nikonos Finder to the housing. Some focus testing would also be needed to see if you would be required to use diopter like a +2, +3 or +4 (close up lenses) inside the dome port.

I attended the presentation in NYC and found it very useful for photographers who are doing more with their work than just shooting for themselves. Try and attend one of the other free sessions if you are able. The tips and resources presented are top of the craft. More to come...

Polina distributed a newer list at the NYUPS meeting on Tuesday Night. The list is published by The Blue Ocean Institute at:

You can download a PDF of the 2009 version. Seems mostly correct. Balanced, not alarmist.

Seems like we, in our Photographer capacity, should, in a respectful manner, when in exotic locations on land, strive to visit local seafood markets and get photos of the slow growing deep water species such as Chilean Sea Bass, John Dory, or other dinner plate specials that are in decline. Those local markets are, at a minimum, "educational." Small Grouper are still sold in NYC's Union Square.

This was the reason for the post. We pay a significant price for not having to pay for film and get the bonus of immediate feedback. "If you want Pictures, shoot film. If you want Work, shoot digital." I haven't shot film since 2003. Only sometimes do I miss the "good old days."

Hi jackiescuba,
I should add this. I spend three hours scanning old stuff this afternoon!
