    I can't get my aperture value below f/5.6
    I'm pretty sure I've hit f/4.0 at one point, but can't remember how I did

    I'm using the 18-55mm lens that came in the kit.

    Not having used the 18-55, I presume that it is a variable aperture lens.
    That means that at the 18mm end you will be aboe to use a lower number
    aperture than at the 55mm end.

    So, as just a simple test, zoom the lens all the way to the 18mm end. Now,
    with the camera in Av mode, set the aperture to the smallest number you can
    get. Is it less than 5.6 now?

    Wow I had no idea that the zoom had any bearing on the f/ value...

    At 18mm, it goes down to f/3.5

    Says on the barrel (and packaging no doubt) sth like: 18-55/3.5-5.6, so now
    you know why. It's also why fixed 2.8 zooms are so popular, most photogs
    don't want the aperture changing every time they recompose....

  5. this, ladies and gentlemen, is the beginning of the tidal wave, the thin end
    of the wedge. this NG will never be the same.


    (oh, and changing the aperture is done via the aperture dial near the
    shutter release button- but control depends on which mode you are in. RTFM.)

    It's not in the FM! The manual only says how to change the aperture... it
    doesn't say anything about variable aperture with the zoom level, as no
    manual came specifically for the lens.

    I know how to change the bloody aperture... It just won't go below f/5.6
    when it's zoomed in all the way, and goes down to f/3.5 when it's zoomed out
    all the way.

    Pardon ?
    The specifications for the lens tell you, you've got things arse about mate.
    f5.6 is the aperture at full extention and f3.5 is the aperture at it's
    wides angle of view.
    Either: 'Trust the force Luke" or develop some reading skills.

  8. This is before even Photography 101. The aperture range of every zoom is
    printed on the front of the lens, as well as no doubt in several places
    throught the "FM".
