If you can't find information about a housing on wetpixel's forums, please check out Digideep.com, which is a database of housings for specific cameras.

As the above link was broken due to migration I have to do some self promo for all the info seekers... just go:

Thanks for the info. Sadly no housing for my camera.

I was having this problem just the other day - finding out which camera's have underwater housings available.

I found Ikelite's site. Pretty in-depth and very useful to search cameras - both compact and SLR. Maybe not the only people who make UWH, but one of the most well-know as far as I know.

thanks.i have the same problem

Seems Digideep hasn't been updated for quite some time? For example they still show no housing for the Sony SLT-a55, while Ike's had one for a while, and the camera's almost end-of-lifed with the a65 "teased" already on rumor sites for a formal release around September/October this year.

I've noticed the same thing. Not much coverage, for new mirrorless cams either.
I wish there were a way for us readers to submit info, and help out.

Or I guess doing it as a wiki, would work...
