Are the IS versions of Canon lens worth the extra cost?

    When shooting sports with the 70-200 f2.8 lenses and using a mono pod
    for support, is the IS version worth the extra money. It appears to
    not be able to increase the shutter speed any to get better stop
    motion under stadium lights. Will these lenses only assist with
    camera shake or will they also help when panning?

    Mine makes a difference. I have a 28-135mm IS and a 70-300mm non-IS.
    Pictures takes under lights at sports events are much sharper with the IS,
    at the same focal length and shutter speed.

    IS for sports is a non-starter. Subject motion blur is the problem and IS
    won't help.

    IS helps for coffee drinkers and old farts (like me) that can no longer hold
    the camera steady.

    Canon's IS has two modes. One compensates for both vertical and horizontal
    shake, the other only for vertical shake. The latter is intended for sports
    shooting when you are panning the camera, so it can be helpful.

  5. If you are using the monopod for stabilisation (versus saving your
    arms), then you can dith the monopod and use IS. The usefullnes of
    which depends on hoe much you move.

    If you ever had camera shake even with the monopod, IS can
    compensate that, too. (Reminder: even during sports, there
    are moments when the players are quite static.)
    IS cannot do that. Only faster lenses, flash, brighter stadium
    lights or higher ISO can do that.
    The 70-200 f/2.8 IS, for example, has a panning mode.

    Subject motion is a problem, but camera movement does not go
    away just because the subject is moving.

    Have yet to see that with my Canon IS lenses. I must be doing something
    wrong.

    IS corrects for camera shake, in my humble opinion.

    There are always the inevitable and specific and unusual and contrary
    examples.

    When you read replies here, please understand that the BASIC question is
    often swamped by answers from the experts who are compelled to add
    irrelevant details.

    Apparently only some Canon IS lenses have the dual modes, so my bad.

    Depends on the generation of the lens. On early ones IS stablized
    both vertically and horizontally without discrimination. Later they
    made it switchable--the 70-300 for example has a switch for Mode 1/2
    where "1" is stabilizing in all directions and "2" is stabilizing
    vertically so that IS doesn't interfere with panning. Later ones
    detect panning without a switch.

    No. Part of the problem in shooting any action is the camera jerking
    around.
    I drink coffee and am starting to get old, and can hand-hold well slower
    than the 1/efl rule, and get pixel-sharp results. IS lets me get even
    slower.

    If this had been written by a newbie instead of by you, I might
    have asked if IS was actually enabled. :) Nikon's VR is initiated
    when the shutter is half depressed and takes about one sec. to
    stabilize. The 70-300mm manual says :
    I assume that Canon's IS lenses have an IS On/Off switch. If set
    to On, is it always on? In addition to the effect of Nikon's VR
    being visible in the viewfinder, you can hear a slight click when it
    engages, and another disengagement click a second or two after the
    picture is taken. Do you hear this? If IS is permanently engaged
    (probably subject to the camera's display timeout) there would be no
    engagement/disengagement click to hear. While not as easily
    noticed, if this is how Canon's lens IS is implemented, you best way
    to test for IS effect in the viewfinder would be to set your lens's
    focal length to 200mm (even better to add a TC to get a greater FL)
    and compare how much jitter you see in the viewfinder with the
    lens's IS switch set to On and then Off. I checked the manuals for
    6 VR Nikkors, from consumer grade up to the 200-400mm VR and all
    mentioned that VR needed to be activated by pressing the shutter,
    and that the stabilizing effect would be seen in the viewfinder.
    This is an example, taken from the 105mm VR Micro Nikkor :
    Are there any comparable statements in Canon's IS lens manuals?

  12. Switching off horizontal correction is a crude way of doing it.
    Panning aircraft and birds often involves non-horizontal panning. It
    wouldn't be difficult to detect panning as any persistent movement
    vector, not just horizontal, and to subtract that vector from
    correction.

    Today's Nikon VR lenses have two IS modes, "normal" and "active". The
    active mode is intended for use in severe conditions (moving platform),
    and panning is automatically detected in the "normal" mode.

    In answer to the OP, I would not wish to be without IS certainly with
    focal lengths longer than 100mm (say) and even the shorter focal lengths
    can allow longer exposure times.

    In a word: probably not. If you are using a mono pod, you'll probably
    not get much benefit from IS. If you are using a tripod, IS might
    actually hurt things. If you can't do it with f2.8 and a monopod,
    then get a really, really big flash.
