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.
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.
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
Conclusion: The Canon PowerShot D20 isn’t exactly disappointing; it’s a competent adventure camera, able to withstand water, shock and cold as well as the next, and take a decent picture under most circumstances, but that’s kind of the point. The D10 was the best in its class when it was introduced in 2009 and had an interesting and unusual design; the new D20 is merely average, with little to distinguish from any one of a dozen rivals.
Pros: GPS that actually works, Build quality, Start-up time
Excerpt: We’ve tested a whole bunch of tough, rugged and waterproof digital compact cameras. They may well be shockproof, freezeproof and dustproof too, but, truth be told, no company has got the full package quite right after many years' worth of attempts.
Cons: Awkward design, bunched up zoom buttons placement, easy to get in finger in front of lens, slow autofocus, lack of user-defined controls (AF point placement, manual shooting), so-so image quality
Summary: The D20 is the easiest waterproof camera to use, thanks to its array of chunky buttons and simple user interface. It delivers decent photos for web use, if all you want to do is point and shoot.
Pros: Very easy to use, Big buttons are ideal for underwater, Tough and rugged design
Cons: Images look rather soft, Videos are grainy, Sluggish performance
