Canon PowerShot A2100 IS

Manual Controls

The A2100 lets you manually choose the ISO setting, set up a custom white balance, and select your metering mode. This isn't a very wide array of manual controls. More advanced cameras would give you granular control of shutter speed and aperture settings, but those features are rare on point-and-shoots.
 

Focus

The A2100 offers only autofucus. The range for autofocus is from 6.4 to 38.4mm (36-216mm on 35mm film) or 1 to 50cm in macro mode.
 

ISO

You can manually set the ISO to 80, 100, 200, 400, 800, 1600. You can also activate a high sensitivity mode, which allows you to access ISO 3200.
 

White Balance

In addition to automatic and custom white balance, you can choose a white balance from one of the five presets. The A2100 lets you pick daylight, cloudy, tungsten, fluorescent, and fluorescent (H).
 

Metering

There are four presets for metering: evaluative, center-weighted, average, and spot. There's also an automatic mode.
 

Shutter Speed

The A2100's shutter speed ranges from 15 to 1/1600 seconds. To get the shutter to slow down to allow a 15-seconds exposure, you have to enable Long Shutter mode.
 

Aperture

The maximum aperture settings are f/3.2 (wide) and f/5.9 (telephoto).

 

Image Stabilization

The A2100 incorporates optical image stabilization to combat shaky hands while shooting.
