    Default Re: Non standard apertures in Digicams

    I'm using a nikon coolpix 5700 at the moment, and it uses non-standard (as compared to 35mm systems) apertures of say,
    f/2.8-f/3.2-f/3.5-f/4.0

    My Qn is simply: Does anyone know if each step increase in aperture of my camera is equivalent to "one stop" in the 35mm systems?

    ie. Is the exposure at f/2.8 at 1sec equivalent to f/3.2 at 2sec?

    Also, does it mean that the usual light meters are useless for digital cameras since they do not use the usual aperture sizes?

    Beginner SLR always use 1/2 stop standard. However, most digital and Pro SLR uses 1/3 Stop standard.

    ie. Is the exposure at f/2.8 at 1sec equivalent to f/3.2 at 2sec?

    f/2.8 at 1sec = f/4 at 2 Sec

    f2.8 to f.3.2 is 1/3 stop increment not 1 stop.
