    Please note, EV numbers simply specify a shutter/aperture combination and are independent of film speed (see attachment).

    However, the sunny-16 suggestion for ISO 125/22 is a good one, because EV-15 is the combination of f/16 at 1/125s, and that is the Zone-V exposure for a film of at that speed in bright sunlight.

    If EV is what you say it is, then what do the 1-19 numbers mean in the Pentax V? Since it's uncoupled, are they just arbitrary values?

    So, by using published data/common knowledge, how should I do the proper markings on the shutter speed plate? I guess, if you just told me what SS resulted from #4 on the value dial @ ISO 100, f/5.6 (for example), then I could do the rest just by using the law of reciprocity.

    Aren't the "EV" numbers on Pentax spotmeters just numbers to transfer to the scale, which then tells you what to set, and not (or rather, only when the 'right' ISO is set) what real EV numbers are?

    On my meter the following lines up exactly:

    ISO 100
    Time 30
    f/stop 32
    EV 15

    Awesome, thank you. Now I have to go about the task of writing very very small.
