    Your engineering skill issovaluable, that you could have made millions
    of dollars, making that modification. It's a crying shame you did not
    have your predictive skills a few years before Nikon came out with the
    new version. Indeed since there are a lot of the old models out there,
    why dont you start a modification service. I certainly would haveliked
    to see such a service.

    Not if I have one of the old-fashioned ground glass screens.
    Which is a not insignificant area. Which part has it selected?

    Say you are trying to photograph the head of a bird. Has it picked the
    eye or the beak? Does it even care?

    No. The camera has no way of knowing what you want.
    My point is that you don't know what the camera thinks you are trying
    to do.
    Say I want to focus on the wart of the end of the nose. Will the
    camera do any better than focus on the face?
    Depends on what you are trying to focus on. How for example does a
    camera decide where to focus in

    The zoom feature (one button push) on cameras with high resolution
    EVF's and LCD's easily beats any optical viewfinder when it comes to
    critical focusing.

    You just have to snipe through the foliage and hit your target.

    3D focussing works in that case there is only the aircraft in the
    picture. How would you get on in the circumstances of

    (not my photograph - this is one of the early shots after the plane
    was reassembled at the Fighter Factory (Norfolk, Virginia)). Would all
    the stuff in the background make it harder for the camera to keep
    focussed on the aircraft?

    or just half-press, but that's not the issue.

    aiming the camera, focusing and then recomposing can cause focus errors
    in some situations.

    none of that will work with a manual focus lens, which was the original
    issue.[/QUOTE]

    Nor is it the situation I had in mind when I made my comments. But its
    worth discussion, just the same.

    especially if you have one of those.

    the nikon d3200 can autofocus down to ev -1 and the d4 can autofocus to
    ev -2. tht's fairly typical of modern slrs although some are 1 or two
    stops worse. still, that's very low light.

    the lens needs a maximum aperture of f/5.6 or faster (and f/8 on some
    cameras, such as the d4).

    good luck focusing on ground glass in those conditions.
    the focus point is not very big.
    where was the focus point?

    it's certainly not any easier with a ground glass.

    i didn't say it did.

    you pick where the active focus point is.
    and my point is that you tell the camera what you are trying to do.
    put a focus point on a branch edge, you pick which one, and it focuses.

    you'll probably want a smaller aperture for a wider depth of field,
    since there's a bit of a range to cover.

    In the case as stated by PeterN it is the issue, as he states above.[/QUOTE]

    that's a different issue.
    i introduced it in the first line quoted above. i could have spelled
    out focus recompose but i guess i assumed people were smarter than i
    gave them credit for.
    he considers most things overpriced failures. nothing new there.

    i never said all cameras had it. more lies from you.

    i simply asked why not use it. if the camera doesn't have it then
    that's the answer.
    so you agree with me, but just want to argue.

    more irrelevant babble.

    no modification is needed. tracking autofocus works fine with the old
    80-400, as well as non afs lenses (mechanical linkage). i've done it
    many times with various lenses.

    select one active focus point and put it on the eye.

    I would use AF "C" mode + 3D-tracking. Once you have locked on to the
    moving target the background is ignored.
    The Mosquito is flying from right to left. The tree line the plane is
    paralleling does not seem to be parallel to your position. So, with
    your pan there is a target which is closing until it is directly
    opposite you at its closest point. If you are using AF "S" or "M" the
    AF is going to depend on your shutter release and dumb luck.
    If you just select a central AF point, your skill in being able to pan
    and hold the AF focus point on the fast approaching plane is going to
    be tested, and dumb luck comes into play again.
    If yo use AF "C" + 3D-tracking, from the moment you are able to target
    the approaching plane an AF focus point will lock onto the moving plane
    (the actual AF point is likely to change as you pan but it will remain
    locked on) and the AF "C" will maintain focus.

    ....and since that isn't your shot, the photographer did a good job
    panning and dumb luck worked well. However, he might well have been
    using AF "C" and some sort of tracking.

    I see. You have done tracking autofocus, with non-af lenses. Or, am I
    nitpicking.
    You do indeed have extraordinary and valuable skills. Would you like an
    introduction to Arthur Morris, who has a contrary opinion, and would
    love to learn your skills.
