Canon WP-DC200s Waterproof Case for A40 Digital Camera - Underwater Photography, Beach & Pool Protection, Travel Accessory

If I had known that it would be SO DIFFICULT to prevent moisture forming inside the case, I would have NEVER bought it.You CAN use it, and water stays out, but you must take care to close it always in front of air conditioning (to be sure inside the air is dry enough). Plus, it's bulky.Much better buying a waterproof camera. That's it.
