Ok!.!.!. you are definitely confused about lens specs!. The 3!.5 to 5!.6 means that is the maximum apertures at the extremes of the zoom ranges!. In other words, at 18mm, your lens has a largest opening of 3!.5!. But you can certainly set it at any aperture other than that, such as f22!. The lens, however, will not allow you to set an opening of say 2!.8!. The same holds true at the other end of the zoom range!. At 55mm, your widest lens opening is 5!.6, but you can set any aperture greater, (higher number), than 5!.6 if you want!.

The relationship between shutter speed and f/stop is called reciprocity, so for any given lighting situation there are reciprocal settings throughout the full range of f/stopsWww@QuestionHome@Com
