Canon PowerShot A3100 IS

The entry-level Canon PowerShot A3100 is based around a 12.1-megapixel sensor, with an optically stabilized 4x, 35-140mm zoom lens. Maximum aperture varies from f/2.7 to f/5.6 across the zoom range. The Canon A3100’s 2.7-inch LCD has a resolution of 230,000 dots.

The Canon A3100’s sensor allows sensitivities ranging from ISO 80 to ISO 1,600 equivalents. Exposures are determined using Evaluative, Center-weighted Average, or Spot metering, and direct control of shutter speed or aperture isn’t possible on this camera. 2.0EV of exposure compensation is available, in 1/3EV increments. Seven white balance modes are available on the Canon A3100: Auto, Manual, or five presets. The PowerShot A3100’s built-in flash strobe has a range of 13 feet at wide angle, dropping to just 6.6 feet at telephoto, and recharges in around seven seconds.

As well as still images, the A3100 can capture video clips at VGA (640 x 480) resolution or below in Motion JPEG AVI format. The Canon PowerShot A3100 stores images on SD / SDHC / SDXC / MMC / MMC Plus / HC MMC Plus cards, and unusually for a PowerShot A-series camera, draws power from a proprietary lithium-ion battery pack. Battery life is rated at 240 shots on a charge, to CIPA testing standards. Connectivity options include USB 2.0 high-speed data and NTSC / PAL standard definition video.

The Canon PowerShot A3100 is available in the US market from late February 2010, priced at around $180
