Like most point-and-shoot cameras these days, the EX-H20G has no optical viewfinder. A 3-inch LCD on the back of the camera serves as your only viewfinder, but it generally does a good job of staying visible in most lighting conditions.

Due to the absence of manual options, the camera's controls are simple and straightforward. On the back of the camera is a dedicated video record button, a dedicated Auto mode button, a playback button, a Menu button, and a 'BS' button that takes you to the camera's Best Shot menu of scene-mode offerings. A round directional control pad surrounds a selector button for navigating in-camera menus.

On the top of the camera are the on/off button, the shutter release surrounded by a zoom control, and the camera's slightly protruding GPS antenna. Two more buttons on the top provide quick access to the camera's mapping and GPS features: One button, which has a graphic of a Fisher-Price-like person, centers the camera's map on your current location. The other button, which has a globe-like icon, displays the shots you've taken on a map interface (as well as the route you've traveled with your camera in hand).

Although you can't set the aperture and shutter speeds directly, the Exilim EX-H20G goes a long way toward making up for that with 28 different scene modes (which Casio dubs Best Shot selections in the camera's menus).
