    Default What's a "Stop"

    i have been wondering about the term "one stop" as in f/2.8 is 1 stop faster than f/4. Perhaps some people an enlighten (pun intended) me

    - why do some people say a stop is 2.0, 2.8, 4.0, 5.6 while others would include smaller increments (2.0, 2.8 3.5, 4.0 4.5 5.6 etc)

    - why is it called a 'stop'? would STEP make more sense?

    - what's it really mean? So if 2.8 is 'a full stop faster' then 4.0, ok, we know we get more light (and narrower DOF) but does this translate uniformly to a shutter speed (eg 1/100 from 1/60)?? I don't think it does but i am at a loss for why we say this 'one stop faster'...

    Happy Friday and hope to see some interesting responses
