Naive question about memory cards.

    Having given my trusty Pentax 43WR to my son to take to Iraq I am in
    the market for a new point and shoot camera and memory card. Some
    advertisements imply that the higher speed cards inable one to take
    better action shots. My question: do higher speed cards have any
    advantage other than reducing the time it takes for the camera to
    recover between shots?

    It depends on how fast the camera can write to the card. It's dependent
    on both the card's speed and the camera's speed. You'll have to check
    with your camera manufacturer. Good luck, I couldn't find out when I
    went looking.

    The other place the speed is important is video writing speed.
    Particularly with cameras like mine that shoot video at 640x480 @ 30 fps.

    Not as far as I've ever been able to discover. The biggest problem
    digital cameras have with 'action' shots is 'shutter lag': the delay
    between you squeezing the button and the camera actually taking the
    picture. This has nothing to do with the sort of memory card installed
    and is entirely down to the design of the camera; different models vary
    widely and for action shots, short shutter lag is a feature you should be
    looking for.

    This site is useful for comparing different models

    Hello,
    Had you sent the 43WR in for the CCD repair per the Pentax service
    advisory?

    Just wondering what your experience was if you did. I imagine the
    climate in Iraq would increase the likelihood of the CCD problem
    ocurring.

  5. Although what you say is true I often switch to burst mode when I know that
    I'm going to take action shots to compensate for shutter lag. In that case
    the speed of the link between camera and card does make a difference on how
    much frames you can capture per second. The card may be the limiting factor
    or the camera. I tend to buy high speed cards to be on the safe side - the
    price difference doesn't seem to be worth bothering. Don't go for
    microdrives - they need more power and are more fragile.
    I second that.

    Kind regards

    Thanks NB for the heads up about the 43WR service advisory. It seemed
    like my camera worked flawlessly. The advisory does not describe what
    problems to expect. Do CCDs either work or fail completely or can
    something more subtle happen?

    Apparently it is not subtle at all. Here is a more comprehensive
    article with pictures.

    I have one of the affected Olympus cameras, but have not sent it in for
    CCD replacement yet.

    Burst Mode: how to just miss the Decisive Moment, rapidly ;))

    If I go out with the intention of catching action shots, I'd use a manual
    35mm camera, not digital. Even 35mm SLRs have too much shutter lag to
    be really confident, although they are a lot better than most compact
    digital cameras.

  9. It depends. There's a place for burst mode and there's a place for low
    shutter lag cameras.
    Sure.
