The Canon PowerShot A590 IS is an 8 MP digital camera that features a Canon branded 35-140mm lens that has 4x optical zoom with Optical Image Stabilisation (OIS). The IS sensors detect the tiny movements of your hands while clicking a picture (this movement is known as "camera shake"), and shifts a lens element to compensate for this motion, which results in a much sharper image at slower shutter speeds than one could get on a camera without IS.
The back of the camera has a regular 2.5-inch LCD that has a resolution of 115,000 pixels as well as an optical viewfinder and buttons to access various features of the camera. Other features include PASM shooting modes, an ISO range of 80 to 1600, support for conversion lenses, and a 640 x 480 movie mode.
