Featuring a 5x optical zoom lens that is completely contained within the camera body, the camera is able to operate and stay waterproof underwater. With a range of 28-140mm (35mm equivalent), you still get a very good zoom range, making it easy to use out of the water as well. Canon has given this camera a TTL Autofocus system that is capable of focusing on images as close as 1cm. away.
Normal: 2.0 in. (5cm) - infinity (W), 3.3 ft. (1m) - infinity (T)
Auto: 0.4 in. (1cm) - infinity (W), 3.3 ft. (1m) - infinity (T)
Macro: 0.4 in. - 1.6 ft. (1-50cm) (W)
To the left of the lens is the small built-in flash unit. Although small, it does have a descent range, up to 11ft. (W). Remember that when you are shooting underwater, the flash range will be significantly smaller since light does not travel as far.
Framing and viewing your images with the 3.0-inch, 461,000 dot LCD screen is a pleasure in all lighting conditions. With 5 levels of brightness and approx. 100% field of view coverage, it is always easy to compose.
The camera's very simple design leaves you with just these three buttons on the top of the camera: Power button, Shutter Release, and Playback button.
To the right of the LCD are the remaining camera controls. First we have the Zoom controls, which also function as the magnify and index option in Playback mode. Directly under them are the video recording button and a thumb grip for camera control. The 4-way controller is used to navigate menus and select images during playback, the FUNC./SET button in the center accepts menu selections. In record mode you press 'Up' to change Shooting Mode, 'Down' Display Settings, 'Left' selects the macro focus and 'Right' changes the flash settings. The FUNCtion/SET button also calls up the Function Shortcut menu. The MENU button calls up and dismisses the main menu screens.
On the right side of the camera you will find a sealed, waterproof compartment that contains the input/output ports. On top is a DC input for an optional power supply. Next are a HDMI output for hooking up to a HDTV. Finally is the USB port that connects the camera to a computer or a TV with the included cables.
On the bottom right corner is a latch system for quickly connecting and disconnecting the camera strap. The strap will lock into place and is very secure, but also comes off easily when not needed.
When shooting with the D20, your images will be stored on either a SD/SDHC/SDXC type memory card. The camera is shown here with the PNY Pro, Class 10, 8GB SDHC card that was used to test the camera.
Powering the D20 is a 3.7V, 1000mAh rechargeable Li-Ion battery. This battery is capable of capturing approx. 280 shots on a single charge (CIPA). Also included is the portable quick charger shown above. This allows you to keep your battery and a spare charged at all times.
