Size and weight are big decision factors when you are trying to find the ideal camera for your needs.
In this section, we are going to illustrate the Canon SX170 IS and Samsung DV150F side-by-side from the front, back and top in their relative dimensions.

Weight is another important factor, especially when deciding on a camera that you want to carry with you all day.
