    Any reason they chose 4 MP? I guess sports/press guys dont need much more
    than that for low quality newspaper/magazine reproduction?

    The message <xAPRa.432312$>
    Larger than 4 Mp would slow the fps rate and reduce the number of frames
    stored in a given buffer.

    8 fps for say 5 secs will catch all the action and be a killer camera in
    sports
    and front line journalism.

    Nikon will not be able to make them quick enough.

    Canon has been "quickly making" just such a machine for a couple years now
    (4.15MP at 8fps). Nikon's slow-and-steady approach to innovation is taking
    a toll on their bottom line in the digital arena (number 5 digital seller in
    the world...using sensors made by others...until this one), but at least
    they are getting back into decent competition in this sector.

    Probably got the idea from Canon by buying a 1D reverse engineering it? It has
    been the dSLR of choice for the sports boys for a couple years now and Nikon is
    finally catching on and catching up.

    I wonder how much longer DSLRs are going to use flapping mirrors, when we
    could be looking continuously at a video screen (through the same
    viewfinder system).

    The message <[email protected]>
    The D1H has a 40 frame buffer at large/fine.
    The EOS-1D has a 20 frame buffer which takes 20 secs to clear so you could
    miss that next shot.

    The D2H will have an enormously large fast buffer.

    Yes its good to see Nikon back in contention.

    I believe that's the case, today. I wonder how much longer it will be...

    From: John Miller
    Also top video equipment uses triple CCDs, a technique that among other things
    almost completely stops colour artefacting on fine monochrome patterns, will
    this ever come to digital cameras too?

    This is exactly what I stated would be announced by
    Nikon in another thread on here. No doubt my critics
    from that thread will be as quick and ready to eat
    their words and apologise as they were to criticise.

    The camera body is the successor to the Nikon D1H.
    The model name/number of its successor is still a
    closely guarded secret, but most bets are on it
    being called the D2H.

    The successor to the D1X will use a different sensor
    with lower speed but more pixels. I have heard
    suggestions of between 8 and 12 megapixels, but my
    money is on something reasonably close to 10 - 11.

    ;-)

    Doesn't look like they copied it. The review mentioned elsewhere says
    the sensor is completely new technology to get the speed and made by
    Nikon.

    Unlikely, as the cost becomes prohibitive for the resolution needed in good
    still image cameras.

    Based on the cost of pro-level DSLRs, I can't imagine that being a problem.

    That would have been an extremely bad idea. Because it would mean that
    the sensor and color filter before it is exposed to light
    continuously. That would have significantly reduced the life span of
    these sensitive components. A color filter will inevitably fade if
    light is allowed to hit it all the time.

    I am very thankful that the sensor and AA-filter of my Canon 10D are
    only exposed to light during the actual image exposure.

    For as long as photographers want to see sharp images in the viewfinder.

    That's what they said in the beginning for video cameras, too.

    They use three CCDs with dichroic prisms that do not fade. The cheaper
    video cameras with matrix filters will fade eventually (sometimes
    rapidly, if exposed to very strong light, such as direct sunlight).

    Kudos to you Tony!

    [snip]
    I wonder if they will use a derivation of their new CMOS chip or just go
    with a nosier Sony CCD? (such
    as a larger version of what is in the D100?)

  19. I don't know who "they" are, but "they" apparently forgot that Video is more
    limited in resolution and bandwidth than still image camera's.
    Besides, Video is not really the topic of this photo.equipment.35mm news
    group.
