Viewfinder (2.5)
The PowerShot SD110 uses a very small real-image optical viewfinder. The viewfinder is not very accurate; what the user sees through it is not what is captured through the lens. I recommend ignoring it and using the LCD screen unless the batteries are ready to bite the dust.

LCD Screen (6.0)
The LCD screen is certainly larger than the viewfinder, but it does not take up the entire back of the diminutive frame. The 1.5-inch low-temperature, poly-crystalline-silicon TFT color LCD screen has 118,000 pixels to form images. It is not as large as it should be, but it is accurate with 100 percent field coverage, so subjects can be properly framed and viewed. Solarization is minimal and can be viewed in bright sunlight with only minimal glare.

Flash (7.0)
The flash can be controlled with the right portion of the four-way controller. The following options can be cycled through: Auto, Red-eye reduction auto, On, Off and Slow-sync. In the normal shooting mode, the camera's flash range reaches from 1.5-9.8 feet. In the macro mode, the flash is effective from 10.6 inches to 1.5 feet. The flash does not light the entire image evenly; it creates a circle of light in the top half of the picture, although the illumination range itself is wider than many other PowerShot models, including the PowerShot A85.

Zoom Lens (6.0)
The Canon zoom lens measures 5.4-10.8mm; in 35mm format, this is equivalent to a 35-70mm lens. This translates to a 2x optical zoom, augmented with an additional 3.2x digital zoom, which should be used sparingly, as it compromises the image quality. The lens has apertures of f/2.8-f/3.9 and uses a TTL auto focus system to focus quickly and quietly. Most cameras in this price range have 3x optical zoom lenses and beyond, as the included zoom is significantly shorter than most comparable models; however, Canon lenses are known to be of higher quality.
