    a simple, yet unanswered question!

    there are 3 raised, equally spaced buttons, just in front of the focus ring.

    what are these for? what do they do? does anyone use them?

    i hope someone knows

    I would love that lens. Did it come with the manual.

    Enjoy, I am jealous

    Those are focus lock buttons. Press any one to lock focus.

    being ignorant, why do you need focus lock buttons?
    is that for manual focus or af?

    focus on a subject, lock the focus and then recompose with your main focused subject not at the point of the focusing grid. example is when you have center focus on and you want your main subject in focus and off to the side.
