    I have a Nikon D-70 with a normal CF card. I was looking at the 24x
    and 80x cards. Will they work in my camera? How can one tell what
    the speed restrictions are for camera's and cards?

    I know faster cd's (24x - 40x) will not work in the older (8x) drives
    - is this the same prinicple or am I mixing apples and oranges?

    Thanks in advance

    Most digital cameras have set write speeds. If the write speed is
    faster than the card, then the card speed will be the limiting factor.
    If you have a card that is faster than the write speed of the camera,
    then your camera will still only write at it's fixed speed.

    eg. I have an Olympus E-10 which writes very slowly, so if I use a
    SanDisk Ultra II card, it makes no difference, as the camera write
    speed is so much slower than the speed of the card. On the other hand,
    my Canon 10D writes at about 6MB/sec, therefore if I use a slow card,
    the camera is limited by the speed of the card, but if I use an Ultra
    II, the camera can write at its maximum, since the maximum write speed
    of the card is 9MB/sec.

    From my experience, any CF card will work in any camera that takes a
    CF card, but it will not necessarily work at its optimum. I'm sure
    your D-70 will benefit from a fast card such as the SanDisk Ultra II.
    Your camera manual may well tell you what the write speed of the D-70
    is. If not, try the Nikon website. Not all camera manufacturers seem
    to make that information readily available, however most card
    manufaturers are keen to tell you the write speed of their cards,
    since they are all trying to outdo each other. If in doubt, buy the
    faster card, since you may well upgrade your camera at some stage and
    you can make use of the extra speed.

    This conversation got me curious and after a couple calls to Canon
    support, I came up empty.
    Interesting was that the first "tech" guy, a Dirk or something similar,
    said that information was proprietary and not released to the public.
    (maybe a breach of homeland security?)
    Second tech guy, and yes I called back, Millard, was very professional,
    and confirmed that it was a specification that wasn't available for
    unknown reasons, and indicated he would pass the customer concerns up
    the chain.
    I indicated that the S1-IS is but an introductory (to digital) camera
    for me and the Canon company was taking an enormous PR hit for no
    obvious gain, and that by this summer when I go DSLR, they would be well
    served to have such simple specs readily available to the public, or my
    choice would likely not be another Canon.

    Even if the camera is slower than the card, if you have a fast USB2.0 card
    reader you will benefit from fast file transfers to pc with a fast card.

  5. What you failed to mention was using a USB 2.0 CF memory card reader. While the write of
    the camera my be limited, the read of the pictures onto the PC will be at the cards speed,
    60x or 80x depending on the CF manufacturer. This is an important factor when uploading a
    gigabyte of data off a 80x, 1GB, CF card.

    Thank you

    Yes I have a 2.0 card reader on a 3.0 ghrz machine so the speed there
    is not an issue.

  7. I have a D-70 and use the Ultra II sandisc 1.0 gig card. This card keeps up
    well with the camera.
    I also heard that the 2 gig microdrive from toshiba works nicely. The
    manual for the D-70 on page 192 gives all the approved memory cards.

    It is if your card is too slow to take advantage of the 2.0 reader...
    And if you ever upgrade to a firewire reader, it'll be doubly
    important.
