    I think that many bodies require at least f5.6 to AF properly. You maybe
    need to cover contacts on the TC to 'trick' it into letting you use that
    combination and AF if light permits.

    The IS will still function with the TCs.

    I agree with Ken... the 100-400 is not the brightest lens to begin with and
    with a 2x will be like looking up a cows bum!
    ....so the AF will be ed.

    Not having a go at you but just an observation....

    I am amazed at the amount of people that are after specific camera gear or
    talking "pro" but make references to lense (sic), Cannon (sic) or flash
    synch (sic). The worst is Cannon. I mean, IT IS WRITTEN IN BIG LETTERS ON
    THE FRONT OF THE CAMERA!!!!!!!!!!!!!!!!!!!!!!!

    Anyway, just rambling on

    Hi Phil,

    It is a great sunny day lens because as soon as you start getting into
    darker areas you have to use faster film/ISO. as the lens isn't the fastest
    at f/4.5-5.6., and depending on your camera you will loose AF when adding
    extenders.

    Having said that, and i am a bit bias, it is a very versitile lens which
    have been very popular in the past, the alternative to it is Sigma's 50-500
    or their new OS lens 80-400, don't remember the details but it is due any
    time soon.

    Depending on what other lenses you have, this will be one that will remain
    on your body most of the summer - you could also get the 70-200mm f/2.8L IS
    and the two converters and then later buy the 400mm f/5.6L, the later is
    sharper then both at 400mm of course! Any lens will degrade with the 2xII!!!
    you will need very good technique to get really sharp images with the 2x.

    there are plenty of info on the net about the various lenses, just go to
    DPReview or Luminous-Landscape and start reading!

    You will have to ask yourself what you want to use this lens for! or if this
    is just to cover all your bases and get the range 100-400, cos this isn't a
    small lens, it is bulky!

    After all this, yes, I have grown to love it though it is not as good as the
    70-200 in its range but better then 70-200+2x! the push/pull design is
    something you have to get used to, it is actually very fast once perfected.

    Now if you are interested I will trade for a EF 400mm f/5.6L+ cash! :-)) I
    told you I was bias!

    best regards

    Henrik

    In article <3faf94ee$0$3502$optusnet.com.au>, PhilM says... 

    Don't bother with the 2x on the 100-400, it'll only disappoint (soft, slow,
    etc). And unless you have one of the more pro bodies, it won't focus with the
    1.4x at 400mm, as you'll be out at f/8.

    I don't have that particular arrangement, but I don't think that
    disqualifies me from making some useful comments.

    You need to make sure that the lens is *sharp* at 400mm, otherwise, a TC
    is only going to get you n-up softness. Using the TC at medium
    focal lengths (200 to 300mm) sort of defeats the purpose.

    A 1.4x TC loses 1 stop of light, optically, and a half stop more shutter
    speed is needed to maintain image stability, totalling 1.5 stops of
    light loss.

    A 2x TC loses 2 stops of light, optically, and a stop more shutter speed
    is needed to maintain image stability, totalling 3 stops of light loss.

    Haven't used it, but the 1,4x extender will make the combination
    something like f6, and the 2x extender will make it soemthing like
    f9.

    Okay for bright sunlight, but ...
