    I just ordered a used Oly 25mm 1.8 via B and H.

    The lens was rated as a "9+" condition.

    My Question Is: What should I look for to make sure I have a "good" copy? (I can return it within 30 days)

    I see folks on the forum talk about lens centering quite a bit. How do I make sure my lens is centered?

    Are there any other things to watch for in a relatively new lens? (I'm sure there won't be fogging/weird rattles/etc.)

    Centering... Take a pic of a flat object, fill up the frame and make sure you're perpendicular to the object.
    Check result to make sure no corner is much worse (sharpness) than the other corners.
