    Then we're in complete agreement. For a video fanatic, the D90
    won't come close to being adequate. As I've stated here before, I
    don't often shoot videos, many one or two short clips every couple
    of years, so for me, the D90's videos would be a big advance.

  2. Good point.

    Except that the resulting images would be only 1MP instead of the 13MP
    still images that cameras can do. And only manual focus as well.

    Hi-def is only hi-def in comparison to standard def TV. Any digital
    camera has far higher resolution.

    Of course it's rhetorical, partly because it's what you are most
    guilty of.

    A welcome direction, but evidently not good enough for you or your
    home video system. You later admit (see below) that even if it
    wasn't a half measure (by adopting 1080p vss. 720p), you'd still
    have found fault with it, and it would still only be a half measure.

    Ah, you're suspicious. Your opinion of your own knowledge is that
    it is clearly superior to Pogue's, but now you're claiming to know
    more than the strobist as well. But they both have theories that
    remain reasonable, while you put more credence in a tax conspiracy
    theory (also, see below).

    True for CCD sensors which read out the sensor's row data using
    the bucket brigade technique, but the D90 doesn't use CCD sensors.
    They're CMOS. Guess again.

    It's all in the assumptions you're making. And the last
    suggestion can't be true because at the lower 720p resolution, tax
    classification wouldn't be a consideration whether clips were
    limited to 5 minutes, 20 minutes or 5 hours, since you're saying
    that 720p isn't considered to be high end video. So far it looks
    like David Pogue's and the Strobist's heat theory still holds up,
    and you'll have to guess again. It probably isn't even a theory if
    they're just repeating what they've learned and for whatever reason,
    aren't in a position to be able to safely identify their sources.

    That's just your supercilious streak acting up. Pouge has a great
    deal of credibility. You fail to take into account that his writing
    is simplified for an audience that either wouldn't want to, or
    wouldn't be able to follow a drier, more technically written
    article. When you learn that CMOS and CCD (bucket brigade) sensors
    have different characteristics, then perhaps your own credibility
    might be reconsidered. Hint: CMOS generally uses less power, so
    wouldn't normally have heat problems. But CMOS is needed for Live
    View, which begets video, and at this point is still seems plausible
    that operating the sensor for long periods at high data rates might
    cause heat problems. Not hot enough to, as you said, "abuse
    pooches", but may be warm enough to degrade image quality. It has
    been noted more than once that in normal shooting, even at very low
    frame rates, and especially with extended half-shutter-press times,
    early pictures are more noise free than pictures taken several
    minutes later due to sensor heating. This isn't likely to be a
    problem with high frame rates using traditional DSLRs, as a burst of
    100 shots will only take about 10 seconds with the fastest DSLRs,
    and 1/2 minute with the slower ones. Not 5 minutes and not 20
    minutes. But it may be a completely different matter if the high
    speed DSLRs take as many shots as possible for 5 minutes, which
    would be 300 seconds, yielding about 3,000 shots. Yeah, it's not
    like video since you'd have more heat due to also having 5 minutes
    worth of energy wasted by clanging mirrors, but even so, I'll bet
    that image quality would slowly decline, and would return to normal
    after letting the camera return to ambient temperature.

    Of course not due to Pogue. As is clearly stated, these other
    limitations were mentioned before I had even heard of Pogue's
    article. And since you've now admitted that you probably wouldn't
    have been interested in the D90 even if it had the 1080p compliance
    that you required, the reason for your bitching about its 720p
    limitation seems to have been just to have something to bitch about.

    As I said, you're a "glass is half empty" kinda guy. A "glass
    half full" kinda guy would have said, "Great. It may not be good
    enough for me yet, but it'll force the other manufacturers to
    compete and we'll eventually see DSLRs with 1080p or higher
    resolution." And if we're *very* lucky, maybe it will even have
    high quality multi-channel sound using external mikes." which I'd
    value more than higher video quality. YMMV.

    Yes, that's consistent with your demonstrated personality. Funny,
    though, that it's not considered to be a personal insult when you're
    the one that says it. :)

    True...

    The only things I shoot high fps are rodeo (bullriding is only 8
    seconds), a baseball batter at the plate or a pitchers delivery.

    I will be intereted to find out how well it works in those situations.

  6. Not at all, when there is a bride camera (Casio's EXILIM Pro
    EX-F1) can do 60 fps at 6MPix and (cropped) movies up 1200 fps
    (and supports full HD, too). And the inbuild flash also cycles
    at 7 fps.

  7. Does anyone actually use that camera? The spec is quite similar to the
    D90 - 1280 x 720 movies at 30fps, the D90 is 24fps, but it does have a
    faster mode as well at HD, and the 1200 fps mode. I wonder how much
    light you need for that?

    It is also 6MP and has a small sensor.
