    Default Camera Lens

    Hi guys,

    I would like to learn more about camera lens, had been surfing for quite sometime but hardly come across any helpful web sites.

    Any intro to websites about lens construction, basic functions, characteristic, comparison btw lenses etc etc?

    In short,

    AF-S = Auto focus lens driven by a Silent Wave Motor in the lens.
    18-70mm = Focal range.
    f/3.8-4.5 = widest aperture for shortest focal length/longest focal length.
    G = Lens has no perture ring on it. Aperture to be set on camera body.
    IF = Internal focus.
    ED = Extra-low Dispersion glass is used on that lens for better image quality.

    For Nikkor lenses you can read up on these two sites.
