What Is the Difference between a Ixus Camera and a Powershot One?
Answer
The notable difference between a powershot camera an Ixus and camera is that the powershot is designed for people who want more control over the pictures they take and has many control settings, while the Ixus is made for people who just want great pictures and nothing more. Ixus are also slim, light and compact while powershots are big and hefty; otherwise the two camera lines are digital and are made by Canon
