Canon Underwater Camera

- trying to outfit my canon g12 camera for underwater photography?
I currently have the g12 with the canon underwater housing, and i would rather not spend 1000 bucks on getting an ikelight housing. However i was wondering can i still some how purchase an external strobe and possibly wide angle lens to use in the cannon housing?

A The Canon brand underwater housing is not exactly optimized for diving like the Ikelite. I have a Canon housing for my G10, but my main use is for kayaking. Anyway, there is no outlet for external strobes. There is a clip-on diffuser for the camera flash, with a leash to help prevent loss. The housing and camera has a positive buoyancy (fine for boating), so for diving you would need to buy the optional weight set. (You don't want to be fighting the buoyancy.) I doubt that the housing has room for an auxiliary wide angle lens. The 28mm (135 equivalent) zoom of the G12 lens should be plenty wide.

- Is my camera an underwater camera? Canon powershot SD1200?
On my canon powershot SD1200, it has a mode called "underwater" but it doesnt say its an underwater camera and I dont really want to test it out in water because if its not underwater, well yeah, itll break. What does the underwater mode mean??

A Yes and no. But, mostly NO. Why don't you have a look in your User Guide...go to the Index (it's on pages 132-134) and look up...Underwater. It will direct you to page 54 and then you will see what the Underwater mode is for. I recommend you read your User Guide thoroughly...and refer to it often if you don't know what is what, etc.
