Conclusion: Big and bold, Canon's first foray into folded optical design was certainly a success, even if wide-angle optical quality suffered a bit. The Canon D20's overall performance put it at the top of both our Waterproof Camera Shootout 2012 and 2013 Best Waterproof Cameras Shootout (Canon didn't introduce a new waterproof model in 2013) in a fairly close race. Its large display performed well outdoors, and the Canon D20 captured good quality stills and video.
Pros: Curvy and comfortable to hold, 28-140mm zoom lens, the Canon D20 has a solid zoom range, Large 3-inch LCD display perfect for outdoor viewing, even in bright sunlight, Simple, easy menu navigation, Diverse array of shooting modes, filters and effects -- including, appropriately, Fisheye, Manual focus capability, Intelligent Image Stabilization, Nice still and video image quality, with good exposure, color and image detail, Full 1080p HD video, but only at 24 frames pe...
Cons: A little awkward to operate one-handed, Bigger than most other waterproof cameras in its class (though this could be also seen as a positive, depending on what you're looking for), No in-camera panorama mode, Power-up, shutter lag and shot recycle times at best average, Chromatic aberration and corner softness were high at wide angle
Summary: Canon's second rugged digital camera is encased in a more conventionally-designed body while providing a hefty amout of protection. The Powershot D20 can be taken underwater to a depth of 10m while being shockproof to falls from 1.5m and freezeproof down to -10C. The D20 features an internal wide-angle 5X optical zoom lens with built-in stabilization paired with a 12 CMOS sensor with ISO 100 to 3200 sensitivity range and capable of capturing full 1080p HD video.
Pros: Low image-noise until ISO 400, Nicely saturated colors, Generally responsive, Good stabilization, Quick optical zoom, Sharp MF-Assist view, Excellent LCD visibility, Excellent rugged construction, Quick shutter-lag, Good battery-life for GPS-enabled camera, Easy to press buttons
Cons: Softness at all ISO, strong past ISO 400, Unusable ISO 1600+, Narrow dynamic-range, Some over-exposure, Poor AWB in low-light, Very slow autofocus, Shutter-release too soft, Impossible to setup video framing, Lens too easy to block, Wrist-strap attaches to wrong side, 2½s Video delay
Summary: The Canon PowerShot D20 is a rugged, waterproof point-and-shoot compact designed for people who want to take pictures outdoors in tough environments and in the water. It's waterproof to a depth of 10 metres as well as dust and shock-proof.
With a 12.1 Megapixel CMOS sensor and a 5x stabilised optical zoom, it can shoot 1080p24 HD quality video and offers a raft of other video modes, including Super slow motion and Canon's inovative Movie digest mode.
Pros: 5x stabilised optical zoom., Designed for purpose., 1080p24 video recording., built-in GPS receiver with track log.
Cons: Very poor continuous shooting., Poor noise handling., No 'door open' warning ., Relatively expensive.
Summary: The PowerShot D20 is a good underwater camera, though it doesn't stand out in any particular area. It takes decent (though slightly soft) photos with pleasing colors (but expect a color cast when shooting underwater). Although light on features, the D20 is water, freeze, dust, and shockproof, and it didn't let us down in our testing.

Summary: The Canon PowerShot D20 has the ability to operate under water or on the ski slopes. It is versatile and durable. We like the dedicated movie button located on the camera that lets you get your best video every time. While the buttons on top can get a little crowded, this camera does a great job helping you capture memories – whether you’re under water or out in the cold.
Pros: The Canon PowerShot D20 has a dedicated movie button located at the back of the camera for capturing videos at a moment’s notice.
Cons: The buttons on the top of the camera are too close together, so it is easy to hit the wrong one by accident.
Conclusion: The GPS-equipped Canon PowerShot D20 is a well-built but large rugged camera with a sharp lens. It produces good-looking images at every supported ISO, but isn't the fastest tough camera that we've tested.
Pros: Sharp lens. Good high ISO performance. Integrated GPS.
Cons: Large, even for a rugged camera. So-so speeds. 1080p video limited to 24fps.
Summary: The Canon PowerShot D20 is a perfect travel companion that you can literally bring anywhere you go. Whether you're into water sports, mountain climbing or just a plain traveller who just needs an extra durability, this rugged camera got your back.
Summary: If you need a camera that is tough enough to withstand the odd knock, and can do a job underwater the Powershot D20 does a fantastic job for the price, otherwise you’re better off looking elsewhere.
Conclusion: Tough cams are an experimental breed by nature, and Canon pulled out the stops with the D20. From the unconventional design to its remarkable lens, this rugged cam easily sits among the best in the bunch. The fact that it shoots superbly underwater will be enough to sell many interested buyers, as should its incredibly easy-to-master UI. Though the D20 won’t woo action shooters and the price might make you a little standoffish, it’s an incredibly competitive camera.
Pros: Great in-camera interface, Sharp lens, Impressive underwater performance
Cons: Moderately slow; not suitable for fast-action shots or video, Unconventional design is interesting but bulky, Unreliable GPS
