Slightly above the lens barrel to the left is the small red-eye reduction/self-timer/tally lamp. Slightly above and to the right of the lens barrel is the AF-assist beam. Below the AF-assist beam, to the direct right of the lens barrel, is the Manual Focus button and the Macro button. These buttons are clearly labeled and stand out slightly above the surface of the barrel for easy engagement. On the opposite side of the lens barrel, near the bottom of the camera body, is the ring release. This allows users to switch between the included lens and accessory wide angle, telephoto, and macro options.
Beneath the movie record button is the Function control for the Canon PowerShot S2 IS. The function button prompts a display of icons on the LCD which represent control over various manual settings; the function button also has a secondary control which allows users to discard unwanted images in playback mode. Below and to the right of the LCD screen is the camera’s metering/jump button. The jump portion of this control is used in playback, helping users navigate through large sequences of prerecorded images; it permits the user to jump 10 images or 100 images, jump by date, or jump to movie. This is a useful feature for those who intend to use large cards (256MB). 
Right Side (7.0)
The Canon PowerShot S2 IS does have a few features on the otherwise smooth right side. The neck strap mount for the right side of the camera body is positioned between the top and right edge of the camera. Beneath this feature is a port cover which sits flush with surface of the right side. This port cover conceals two terminals, a DC in terminal and a digital terminal for either PC or printer, when connected via a USB cable. Below these two ports and concealed by another flimsy plastic cover is the memory card slot.

Top (7.5)
On the top of the camera body is a flash/microphone button. Don’t let this label fool you: this button will not release the closed pop-up flash. Instead it cycles through flash settings when the camera is in recording mode. When in playback/review mode the button serves its other function and provides the means to record audio clips up to 60 seconds in duration to accompany recorded images. It is also possible to record stand-alone audio clips that may last up to two hours, depending on available memory and previously established audio parameters.
To the right of this button is the camera’s flash. While the in-camera flash is a pop-up unit, it will not rise automatically and must be manually engaged. This design may be frustrating during certain shooting situations, or just frustrating, period to those upgrading from point-and-shoot models. The flash is positioned directly above the lens barrel of the camera and should provide even flash coverage without heavy weighting of shadows to either side. To the right of the flash is the shooting mode dial. The mode dial protrudes slightly, with its edge facing the back of the camera, a helpful arrangement in regards to accessibility and control.
To the right of the mode dial are two control features, one inside the other. Positioned in the center is the off button for the camera. Interestingly, this off button does not turn the camera on. For the camera to be turned on, the user will need to move to the second feature located on a ring that surrounds the off button. This settings ring allows the user to move between power on, record, and playback modes via the mode lever positioned on the ring. This feature is a bit frustrating, although users will surely adapt to it over time.
Moving up the right side of the camera body and out onto the top of the right-hand grip, users will find the drive button, controlling the self-timer mode and continuous shooting options. At the front of the right-hand grip and positioned on a slanted plane is the shutter release button, which is nestled in the center of the zoom lever. The lever is in the shape of a ring, with a small tab that moves left and right.
