While I was wondering around on eBay, I came across this underwater housing for Leica Digilux 2 camera. The manufacturer is Hugyfot and they have this posted on their website from 2004:
Hugyfot Belgium is contacted by Leica for the development of the Leica Digilux-2 housing. It appears to be dead on target and the pretty design of this housing enjoys a lot of admiration and attention. More and more digital cameras appear at the ‘underwater’ scene and Hugyfot decides to only focus on the development and production of housings for digital SLR-cameras.
