The PowerShot and Ixus are two lines of digital cameras produced by Canon. Ixus is intended for those who want to take quality pictures of their family and friends. It may also be useful to carry you to important events such as weddings or birthday parties.
Powershot was explicitly created for those interested in detail and photography art, and it is fun to play with the controls. Ixus camera is easier to use, and they are also small enough to carry without any fuss. Powershot camera is much bigger and heavier.
Powershot was intended to mimic the look and feel of the professional level DSLR cameras. Powershot features a lot of controls, which provides the user with the freedom necessary to create the perfect picture because of their professional functionality. Ixus, on the other hand, is simple, with only a few settings. It is also more convenient and lacks the complexity and busyness that typically confuses people.
