    Something like the Olympus E-330 has for live preview. Only instead of
    or in addition too, they'd have an electronic viewfinder that could
    "swing into" the path of the optical eye viewfinder. This would allow
    the mirror to be lock-up during high speed continuous shooting,
    allowing for much faster FPS rates, possibly in the 20-30 range,
    depending on the limitations of read-out speeds from the sensor or
    cropped sensor area. This would require a second, smaller monitor
    sensor, much like the E-330 has. It would also take some of the strain
    off the whole camera mechanism and lessen battery use.

    The whole concept of an SLR renders the "live preview" moot. Adding live
    preview would do nothing but increase the cost of the camera.

  3. but that would convert SLR to video camera. Get decent one and you'll get
    20-30 fps...

  4. If you get 30fps then you are going to have the added problem of making sure
    the cache will hold 6 seconds of shooting at this rate! You are talking
    180 frames! Also think of the daunting workflow dealing with so many
    shots.

    If you want these sort of features so much why not just buy a camcorder,
    30fps of poor quality shots, will that make you happy?

    Not if you are a sports or other shooter of that kind. You'd only be
    looking for "the" action shot, not worrying about the minutae of
    sharpness or detail-level of each image.

    Don't you Canon shills ever get tired of barking against features that
    will inevitably find their way even into your cameras? Dust control
    has arrived (whether Canon's actually works is a question) and 30fps
    need not be poor quality. If some sports shooter is only utilizing the
    centre 50% of their frame now, and Canon decides to do something to
    punch up the speed, the shooters will jump on it.

  8. The problem, at least with current technology, is that the
    pixel processing rate would be huge: 12 megapixels at 30
    frames a second is 360 megapixel/second processing, including
    the jpeg compression for the view. That's about 4 times faster
    than the current fastest camera, the 1D II N.
    Maybe someday.

  9. The "good shooters" fill the frame.

  10. And, oddly enough, they all have and use actual cameras!

    Don't you ever get tired of defending your asinine fantasies?

    Any "sports shooter" who needed that kind of speed could grab any
    decent digicam and get both an electronic viewfinder (no mirror lockup
    necessary) and 15+fps. The professional shooter would grab the right
    tool for the job: a video camera.


    What I found most interesting and odd is your assumption or assertion
    that your fantasy contraption would "lessen battery use." How? It not
    only has an electronic viewfinder with a "swing into" mechanism,
    whateverthellthatis, it also has an additional monitor sensor; and it
    has to process the flood of images.

    Gee, one retard said video was no good, another was supporting it.
    Which one to denigrate first?

  14. Apparently not. But Rich is pretty smart, so they may not be fantasies.

    What does seem to be Rich's game, though, is to start flames or at least
    heated controversey. He does this in a number of ways, which are
    observable over a short time span.

    Why he does this, no one can say. Sometimes he's brilliant, but
    frequently creates a lot of bg noise.

  15. Why he does it is easy to say. His mommy and daddy didn't pay attention
    to him unless he misbehaived, so he craves attention, and that's the
    only way he knows how to get it.

    Flames are not started by posters posting things about DSLRs, they are
    started by people taking taking things personally and reacting.

    YOU, of all people, calling someone a retard?
    Pot, kettle, black; these are three words which immediately spring to mind.

  18. Pot, Kettle, Black!

    Pot, kettle, black, though, is better grammatically.

    I wasn't supporting using a video camera for still images; I was
    pointing out that the camera your need-for-speed fantasy "sports
    shooter" needs already exists.

    Oh, and AUK is over there, bonehead.

    Olympus E10 and E20 used a beam splitter to give simultaneous views to
    the eye and the sensor chip. Always seemed a worthy approach and it
    would be a more elegant way to get your unblocked viewfinder and low
    battery consumption. Sensors have improved a lot since the E20 so a
    current implementation of this design would be a 'killer app'. -Guy
