Camera Overview — Canon PowerShot A40

The Canon PowerShot A40 is a 2-megapixel point-and-shoot digital camera built around a compact plastic body measuring 110 x 71 x 38 mm and weighing 350g. It captures still images at a maximum resolution of 1600x1200 pixels in the sRGB color space, with a burst mode capable of up to 2.5 frames per second — a useful feature for capturing fast-moving subjects at this resolution tier. The autofocus system uses contrast detection with 3 focus points, providing straightforward and reliable focusing for everyday shooting situations.

The camera features a 1.5-inch fixed LCD display with 120,000 pixels of resolution alongside an optical viewfinder, giving shooters two ways to frame their shots. ISO sensitivity runs from 50 to 400, offering a modest range suited to well-lit environments. Storage is handled via CompactFlash cards, and the camera connects to a computer via USB.

Power comes from four AA batteries, with an estimated 500 shots available when the LCD is off using alkaline cells, or approximately 120 shots with the LCD active — though performance improves with NiMH batteries. A built-in flash covers a range of approximately 2.5 meters with modes including Auto, Red-eye Reduction, On, Off, and Slow Sync. There is no image stabilization, no Wi-Fi, and no Bluetooth connectivity.
