Thread: f stops on lenses

    Default f stops on lenses

    Hi all,
    would like to ask this question.

    say a 18-55 lens has a f3.5-5.6 f value

    so why can it go all the way to 3.5 at times

    but other times only till 5.6 ??

    juz something to clear up your confusion. its at f3.5 when at 18mm, and can go up to f5.6 at 55mm ... its not a matter of different fstops 'at times', as it varies according to your focal length.
