    If I use 2 different lens a 50mm at 2.8 and a 80mm at 2.8, with all else being equal, will the DOF area be the same, or with one of them be more shallow?

    80mm will be more shallow, though probably not by much.

    Three things contribute to DOF:

    1. Distance from subject
    2. Focal length of lens
    3. f/stop
