For anyone keeping track of Canon's waterproof camera range, you'll realise that it has been quite a while since the company's first model, the D10, made its debut. Since then, many other companies have made inroads into the space, delivering models with snappy performance and decent image quality, to boot. So does this newer model, the D20, have what it takes to stand apart from the crowd?
Design and features
The D10 was a curiously-designed beast, with rotund corners and a bulky shooting feel. The D20 is much more refined, and fits neatly into the hand without the risk of slipping out. It has a textured black plastic on all sides, while the buttons at the back are nice and large, making them ideal for underwater use.
Of all the waterproof cameras that have passed through the review process at CNET Australia, the D20 is without a doubt the easiest to use. The large buttons contribute to this, but it's more the menu system that makes this a no-fuss and painless user experience. Automatic mode is activated by default, but to enter into Program or any of the other scene modes, it's a simple matter of pressing the top arrow button on the four-way directional pad and then select your option.
The chunky buttons are textured too, which makes them easy to grip.
At the top of the camera, the design is kept similarly simple, with a large power, shutter and playback button. The side doors are locked with a rugged toggle switch, covering all the important ports like mini-HDMI, USB and the battery/memory card compartment.
The D20 comes equipped with a GPS, which is easily activated or deactivated from the menu. Unlike some other cameras of this class, there's no option to drill down a little deeper in the geotagged information the camera can display on the screen and store with the image — for example, there's no options for appending city or landmark details in the EXIF data. You can, however, keep a track of your route using the GPS module, and plot this using Google Maps.

Canon rates the battery at 280 shots.
The D20 produces shots that are fine for small prints or resizing for web use. It might be tricky to make decent enlargements from the photos it produces, because of the over-processing artefacts present on some images. The lens shows quite a bit of fringing on high contrast areas too, which can be difficult to hide in larger prints.
Colours are bright and punchy, with the D20 delivering accurate exposures that fall on the mark in most situations. Noise is kept under control until around ISO 400, when it starts to make an appearance in shots. It doesn't become a real problem affecting the clarity of shots until ISO 1600.
