The PowerShot ELPH 170 is a 20-megapixel camera with 12x optical zoom and a 35mm-equivalent focal length range of 25mm-300mm. It has a 2.6-inch LCD (230,000 pixels).
Because of its small size, we consider this model a Point-and-shoot camera.
The PowerShot ELPH 170 stores photos and video on SD/SDHC/SDXC memory cards but has no on-board storage. It captures images as JPEG files at a top resolution of 5152 x 3864 and HD-resolution video as MOV files at a top resolution of 1280 x 720 and a frame rate up to 30p.
Like most digital cameras, this model comes with a proprietary rechargeable battery. The image stabilization system for this camera is optical.
The PowerShot ELPH 170 measures 3.9 inches wide by 2.3 inches high by 0.9 inches deep, and weighs 5 ounces (with battery, memory card, and strap).
ViewfinderThis optical device allows you to look through an eyepiece to frame the subject before taking a picture.
Manual focusDigital cameras provide greater depth of field than cameras with longer focal-length lenses, such as 35 mm or APS cameras; therefore, manual focusing will rarely be needed. It's not even possible to do on some cameras. Manual focus options vary; a few cameras provide a continuously adjustable manual focus ring, others only a limited number of discrete focus distance settings.
Exposure compensationAllows for minor adjustments to the automatic-exposure settings. When a scene has high contrast, as in a backlit scene, automatic exposure may not achieve the effect you want. It helps to be able to alter the settings so that the subject of the photo does not appear too dark or too light.
Image stabilization type
Image stabilization typeAn image stabilizer compensates for handheld camera shake. Optical (in the lens) and mechanical (in the camera body) image stabilizers are the best types to use, although some cameras include simulated stabilization, which is considered a less effective type than the others.
Touch screenTouch screen indicates touch capability on the LCD.
Manual controlsSome cameras allow the user to set the aperture (f-stop), shutter speed, or (usually) both. This feature is used to override the automatic exposure settings when more control is needed. During a sporting event for example, you may want to use a high shutter speed to freeze the action. Or, you may want to use a low shutter speed to blur moving objects (like a waterfall) while keeping stationary objects sharp. Using shallow depths of field can be used to blur the background of photos while keeping the foreground in focus. Typically up/down arrow keys are used to change settings displayed on the LCD or in the viewfinder. These controls are not as easy to use as on conventional film cameras.
Macro focusThis is a setting that allows you to take extreme close-ups, from a few inches to only 1 or 2 feet away from the subject. test
EyeglassesDenotes cameras with a viewfinder diopter adjustment, which allows some eyeglass wearers to take off their glasses when using the camera.
Maximum apertureThe maximum aperture (lens opening) for wide and telephoto shots. A single number indicates that the camera does not have a zoom lens.
Shutter speed range
Shutter speed rangeShutter speed controls the length of time that the camera lets in light to expose the camera's sensor. This specification shows the range of selectable shutter speeds by defining the minimum and maximum shutter speeds.

Optical zoomOptical zoom is the maximum magnifcation of the lens.
35mm equivalent zoom ratio
35mm equivalent zoom ratioAll digital camera manufacturers publish this "35mm equivalent" focal length simply because people are used to hearing it and knowing what kind of image a 28mm lens produces compared to a 50mm lens.
LCD sizeDigital cameras have a small liquid-crystal display (LCD) screen on the back so you can see the images and decide which to keep. You can also use the LCD to help frame photos, but that's a sure way to run down the battery in a hurry. Most LCD screens are too dim for viewing clearly in sunlight. Many cameras also use the screen for displaying menus and camera settings. It is desirable to have both an LCD display and a viewfinder with an eyepiece.
AA batteriesIndicates whether the camera accepts AA batteries. This options allows you to use disposable or rechargeable batteries.
