Maybe the CF should die?

    Isn't the XD proprietary, like the Memory Stick? In that case, no, it
    shouldn't. We have had cards in and out lord knows how many times, and
    never bent a pin. I'm not sure how others do it, it may be a design flaw in
    some cameras, possibly too wide a tolerance in the slot?

    Same here, using several different really cheap card readers etc. I wonder
    if these morons are -forcing- the card in backwards? After seeing some
    idiot somehow plug a firewire cable in backwards, I'll believe anything!

    I've seen how SD cards mount in a Palm device, they are partially
    exposed and can be "released" by accident. Do they mount differently
    in cameras?

  6. Why not the more common SD cards, rather than a semi-proprietary xD card.

    Why not good, old-fashioned CF cards?

    We don't NEED anything smaller - CF cards are very robust - usually cheaper
    for the same capacity, and the larger physical format means they can cram in
    more memory at the same density, for a higher-capacity product.

  7. The SD would now be my choice. In cameras I've seen the mounting is quite
    secure and not "partially exposed". The card is hidden behind a closed
    door.

    CF cards now go up to 8MB. One MB cards are relatively cheap.

    I don't understand the need (desire) for smaller cards, myself. The CF
    card is just about large enough to not get lost amongst the keys in the
    pocket (in a case). It is small enough that a half dozen don't pouch
    out a shirt pocket very much. It is large enough to be easy to get in
    and out with a fingernail on its ridge.

    Bending pins? I guess it's possible, but I'm not exactly Joe
    Coordination, and I've never bent a pin, or even felt in danger of
    doing so.

    I have to wonder if the smaller cards aren't just manufacturers
    attempts to keep the market built up, to continue selling at higher
    prices, and to sell new, but unneeded, products just because they're
    new. In other words,what are the real advantages of SD and xD cards?
    Are there any or are the just gimmicks?

  9. I have to wonder if the smaller cards aren't just manufacturers
    I can see a use for, say, SD technology in such things as my PDA, but in SLR
    cameras I just can't see the need. Some memory is so thin it's actually
    quite scary taking it out of a camera :(

  10. Why? Because SD cards have many fewer contacts, and each contact has a
    much larger area. The contacts are a wiping leaf rather than a very small
    pin and socket, so an SD card has the potential for a higher reliability
    and ruggedness.

    There really is little difference in price, although you are right about
    the greater volume which may help some people to handle CF cards, and
    could allow a greater capacity.

    Can't say I've EVER had a reliability issue with either formats.
    Off the top of my head I think SD are up to 2GB and CF 8GB.

    It is much worse to lose 8 gig then 2 gig of information.
    I think many photographers would rather split there work up to limit the
    possiblity of loss of images to just one media.

    It's a good theory, but in reality it's not the SD card that has the
    issue, it's the SD card slot in the camera. They use a mechanical
    switch, similar to what's in a cassette deck, to do write protect. This
    switch can get damaged, and make EVERY SD card unreadable because the
    camera thinks that the card is write-protected. You can just dump the
    camera if it's a P&S, but for a D-SLR, you're looking at an expensive
    repair.
    In the higher capacity cards there is a big difference, at least
    percentage wise. I.e., I recently purchased a 2GB 50x CF card on sale at
    Fry's for $100. The 2GB SD cards don't go on sale for anything close to
    that, selling for around $180.

    In
    I am not aware that a WRITE(or Delete)-protect switch prevents READING the
    picture data off the card. Only in trying to WRITE/DELETE new image data
    does that become a problem if the switch goes faulty.
    It's also a question of card read and write speeds too. Much more important
    for the sports action photographer than the studio based one, though. IME,
    the SD cards generally don't (yet) perform at the same speeds as the CF
    cards.

    Yes, my mistake. I should have said make EVERY SD card _unwriteable_.
    The camera is unusable, except for reviewing pictures already on the SD
    card. Just saw a Usenet post about his happening. If you see one post
    about something on Usenet, you can be pretty confident that the
    problem's been seen pretty often by the non-Usenet world.

    Just as we see postings about problems with CF cards where the pins have
    been bent in the camera requiring an expensive repair. Both of these card
    types can be abused, but I know which I now trust the more.

    When I was looking at 1GB cards, 60X/66X speeds, I found the cost was very
    similar.

    Cheers,

    A friend of mine bought A D70.

    She immediately put the card in sideways and bent a few pins. Nikon
    repaired it for CAD$125, which I figure is very reasonable.

    I like CF, and hope that it will continue to evolve for the next 10
    years.

    And although I really don't like microdrives, it is the format that is
    most likely to have the greatest memory of all the tiny storage devices
    for quite a while.

    Cheers,
    Alan

  18. As long as you don't bend the pins in the camera, which I've seen several
    people's postings complain about.

    I do believe SD is now becoming the media of choice, except in the realm of
    DSLRs, and even there, there are DSLRs that support SD, either alone or in
    conjuction with CF.

    Not sure I understand what you mean by sideways. Do you mean 90 degrees
    off? I don't see how if one takes 30 sec to familiarize themselves with
    the D70, or a 990/5700 by my experience, how one could bend the pins.

    Ha, the best part of that thread was where they call the 8080 "pro level
    gear."
