    Quick question, " Its true that a higher f stop will give you more depth of field. What makes the 70-200 f 2.8 a good lenses for shooting fast action sports?"

    Im learning just like you are or like you did back in the day.

    Higher numbers ( smaller apertures ) like f16 will give you a lot more depth of field compared to lower f-stops. This however, cuts down the available light that reaches the sensor so a longer shutter speed is necessary to create an image with "proper" exposure .. with a larger aperture such as 2.8 more light will be able to hit the sensor which means you can use faster shutter speeds that are desired to shoot sports to "freeze" the action.

    Larger apertures will create a smaller DoF, but there are also other variables such as distance to subject and distance from subject to background etc... Search around a little bit for more in depth info.

    Also keep in mind the 70-200 is not designed specifically for sports. It's actually not very good at sports unless you are close to the action.

    The 2.8 comes in handy when using it for things like portraits.

    Just because a lens can go to 2.8 doesn't mean you have to shoot it at 2.8. A lens is actually sharpest when closed down two stops (5.6 in this case).

    With D80 x1.5 crop, the 70-200 is 140-300. So depends on which sports you want to shoot BUT do take your distance from action into consideration.

    If you are shooting across-field (or court) and you are close (sidelines) it will suffice. If you are shooting down-field you will need something longer.

    Yes it will, unless you are willing to spend this kind of money.

    Canon EF 300mm f2.8L IS $4499.00
    Canon EF 400mm f2.8L IS $7190.00

    Fast action requires fast shutter speeds. Fast shutter speeds are easy to accomplish in daylight, not so easy under the lights.

    Also, for most sports shooting a shallow DOF is preferred to make the action pop from the photograph. Easy to do on a football field, tougher on a basketball court, especially if you are shooting from the courtside/baseline area.
