    I see that a wireless USB 2 spec is being finalized. I'd love to have a
    wireless device go under my camera, hook up to the USB port, and DL
    directly to a computer or laptop not too far away. The USB cable
    supplied with the camera is very short (5 ft) and the max length of USB
    (by spec) is 3 or 5 meters (depending on speed).

    Wireless capable of, say, 20 - 30 metres would be dandy.

    But the camera would not have the drivers needed to drive a wireless USB interface
    therefore -- forget the idea.

    If properly done, the camera would not even know the wire was missing.

    Otherwise, K-M would sell an adaptor to do the job, I would be just as
    happy.

    I agree,, for instance my 20d comes with software that operates the
    camera when tethered (usb cable). As a black box - the wireless
    replaces the usb and is developed to handle and transmit the
    camera output. It's drivers in turn are used pc/laptop side to
    hand off to the computer -which then applies the camera drivers
    /or generic drivers to the cam's original output (per sae) sig. Thats
    the purpose of driver - to relate to the kernel which relates to the
    overall os (old techanyway). A pipe is a pipe kinda idea. I think it's
    exciting. I would love to be able to take, say, landscapes or work in
    the field with a laptop and use the comp to configure the cam - and
    view it's output on a big screen. I would like to see a mount for a
    tripod integrated into this(servo)..and then this system utilize
    software to take multiple and coordinated images - and combine them;
    and in this fashion greatly multiply the camera's capability for dof,
    image size, color attribute..you name it. It's not a new idea, but
    would be a new aplication to the private "small"user of technology.

    The was a thread previously that debated the the virtues of particular
    format lens and sensor sizes. The notion that the camera can be
    extended via this type of system i think in the long run is salient.
    The addition to further logic and memory environments, and
    associated mechanisms offer some immense capabilities.

    The networks are an example of this type of solution.

    The economics of propriety and that of demand seem to have the final
    say; and there are examples on both sides of the aisle.

    But to digress..can be done.

  5. It *shouldn't* require any drivers. It would likely require some sort of
    configuration, much like WEP or LEAP on wireles lan. But this could be done
    on a PC and then connected to camera.

  6. Get a high end Nikon (D2H/D2X) or Canon DSLR (1D/mark2, 1Ds/mark2), they
    already have an attachment that sits on the camera, and transfers files in the
    background via 802.11.

    Another option is to get two memory cards and a Jobo Giga Vu Pro portable
    storage device (PSD), which can use an 802.11 compact flash card. Upload the
    first card to the PSD, and then switch to the wireless card and upload the
    files to your laptop while shooting with the second card.

    I await your cheque in the appropriate amount to support my needs. That
    should include replacements for my glass as well: 20mm f/2.8, 50 f/1.7,
    28-70 f/2.8, 100 f/2.8 macro, 80-200 f/2.8 and 300 f/2.8.

    I'm sure that an add on mass-market device will be much less costly.

    Cheers,
    Alan.

    Something like a CF card (that can fit the majority of DSLRs) that is
    capable of doing a 802.11 store-and-forward would be neat.

    Either way. I'm shooting a small fashion show in a couple weeks. It
    would have been cool to wirelessly transfer the images to a laptop and
    simulataneously project the shots on a screen on the side. (In the
    remote storage mode of the camera). As it is I'll have a sync cable in
    my way...

    One thing I am sure of: Technology *will* catch up. With a broadband
    net connection and the right hardware, the images will be appearing at
    the agency's desk seconds after you press the button.

    For a joke, take 50 or so images with a really tight DOF, all focused
    on the girl's breasts / guys pants and submit them as the complete set
    - just to see the reaction you get. Ahh, the fun of digitoys...

    I would think that if your cam supports real time usb connect - Like
    the 20D with eos capture, then it's feasible to do. Fixed cam to cover
    a field, tether (usb cord) to laptop and capture util; and laptop set
    to external video monitor...(you'll see it on the laptop too
    generally. At that point...there are video wireless remotes (rabbits
    maybe). The essential is - does your camera do this? and can
    you operate the laptop. Otherwise it gets more involved.

    I agree a truly integrated solution would be better. It's fun to
    dream.

  13. Check out how slow most camera USB ports are (USB 1.1 or even slower). And I
    suspect with most of them, the camera cannot be used while the upload is taking
    place. So while it would be possible to build such a device, it is likely to
    be too slow to use. At least with the 2 card method I menioned in the
    paragraph you clipped off, you only need to divert your attention twice (once
    to copy the card to the local disk of the Giga Vu, and a second time to start
    the upload process).

  14. The problem is most cameras that I'm aware of want the memory card door closed
    in order to operate (and Panasonics put the memory card door underneath the
    camera). I suspect you would need more space than a current CF card allows for
    anntena, and whether there is enough juice provided by the camera to do radio
    waves is another question.

    One consideration might be the effect on battery longevity, as
    it will be drawing power which could go towards shooting images. Unless
    the add-on device has its own battery, in which case it might even help
    support the camera. :)

    Enjoy,

    I already have a sync cable to contend with. (Job has too small a
    budget to rent wizards), I'm not going to add a tether to a PC. I don't
    need to operate the laptop. The K-M software for remote store will also
    put up full screen views as you shoot and store. You can completely
    ignore it while you work. The supplied cable is 5 feet long (or rather
    5 feet short).

    I don't think it's a dream, just a solution that isn't cheaply available
    yet.

    Cheers,
    Alan

    Hmm ... the Nikon D70 has no sensor on the CF card door, and
    will happily take shots with the door open.

    Also -- the door (like most of the camera body) is
    Polycarbonate, so it should be pretty transparent to the RF from the
    card.

    If you need more space, the door is secured by two small
    countersunk Phillips-head screws, so it could be removed with a proper
    sized Jeweler's screwdriver. (But a card sticking out that door might
    be awkward anyway, as it will be poking you in the right cheek -- unless
    you are shooting left-eyed, in which case the card may well be sticking
    its antenna up your nose. :)

    You could also get a spare door, which you could modify to
    accept a right-angle MicroDot RF connector to lead off to the antenna.

    But unless it was made for the camera, I suspect that
    configuring it with the drivers and the IP address (plus encryption
    (WEP) keys) would be a pain. External hubs tend to have flash memory to
    retain these settings, but I think that most PCMCIA cards require the
    computer to tell them what their settings are at each power-up.

    But -- even if these problems are overcome, I still worry about
    the drain on the camera's battery during shooting and transmission.

    Enjoy,
    DoN.

    USB 2.0 in my case (Max 7D).
    This is true, but with USB 2 it will be about 1/2 - 3/4 sec per image
    (RAW+JPG) which is faster than my strobes recycle at 1/1 or 1/2 power.

    (USB 1.1 which I'm running right now (PC) does RAW+JPG (about 12 MB
    total) in less than 2 sec which is still faster than my strobes at 1/1).
    What I will be doing is a two card dance with a laptop and willing
    assistant (2 or 3 beers is all the pay he'll take). But when the
    technology allows, and it innevitably will, I will have a reasonable
    cost wireless solution for situations where a shots budget is
    impractical to calculate.

    It'd be nice if it came with a free pony, too. ;)

    (You wouldn't be able to fit the aerial parts into the CF form-factor,
    much less fit in the flash memory, etc, as well. There's also the
    problem that the signal would be badly attenuated by a typical CF card
    slot.)
