Canon a570 is for beginner

Hello all,

I have searched and not really found an exact answer for my question.

Basically, I want to buy a cheap digicam and housing for some underwater photography. At first, I was set on the S90 or G11 and canon housing, but for beginning, and about to get married, and I want a DSLR for dry photography, I want something cheaper.

I figured a camera/housing setup will be under $200, I understand some strobes will work with fiber optic cables and whatnot, but my main question is, with the Canon housing, are there any wide-angle adaptors available or that I can make work?

Thanks for looking

I have an A570 which I bought brand new on E-bay for $75, and a Canon housing - which I bought from Canon ($70) when they had a special last July.

I then got a Sea and Sea YS110 alpha which adds hugely to the quality and color of the pics that you are able to take. Recently I bought Inon lenses - AD Mount base - close up lense UCL 165AD, wide anlge UWL 105AD, and fish eye UFL 165AD - I am so happy with the pics this set up produces that I recently went out and bougt an additional A57 as backup.

I also have a dry Canon SLR, but having had a housing flood a few years ago - I am just not brave enough to take it under water.
