I showed you the new Canon PowerShot SD780 IS Digital ELPH Camera in the previous post. Now I want to show you its first accessory that will make the camera waterproof – the Canon WP-DC31 Waterproof Case. The case is designed precisely by Canon for the SD780IS camera. But you need to break your wallet for $181.60 if you want it. As the camera itself costs you for about $280, it means you must pay for about $461 totally. I think you need to consider the PowerShot D10 if you really need a waterproof camera, as it just priced at only $330.
