    You could tell us more, like what kind of camera you are using and
    whether or not you are using tele-extenders.

    In the mean time I note from http://www.dpreview.com/reviews/tamron-150-600-5-6p3
    "... he lens has a decidedly slow maximum aperture, starting at F5 and dropping to F6.3 at full telephoto". This could have something to do
    with your problem.

    Thanks for replying. It's on a 5D Mark II. Aperture, shutter speed, VC on
    or off, even on a tripod, makes no difference. Of course at f22 it's less
    out of focus but still unacceptable. Also, it's not confined to max focal length, although at shorter focal lengths it's marginally better.
