    How does 1.8 or a fast lens differ from an f/4?

    That's about a tad 3 over stops faster.
    1.4
    1.8
    2.0
    2.8
    4


    It allows more ambient light in so that you can use a faster shutter speed.

    Bigger hole, more light, creamier bokeh.

    but also a more shallow DOF. You need to be aware of your distance to your subject in relationship to your f#.

    1.4 is the next full stop under 2, so 1.8 is like a third or something like mob said.
