  1. There's nothing wrong with the sensor itself, but the artifact that can be seen there fits with the explanation MattH gave: the camera has not one but 4 sensors in an array, and so in the 0:53 second on that video you can see that the light overload coming from the sun causes smearing in only the upper left sensor (out of that 4 sensor array) and so the smearing is cut in half, which is very odd.
    Apart from that the sensors look fine to me.

     

    Oh, I though that was me...   Anyway, within the issues with this camera is the fact that it needs to be "calibrated", supposedly for avoiding the quadrant artifacts: differences in exposure between quadrants; differences in shadows between quadrants; mirroring, wich is a "ghost" of a light in the opposite quadrant (this is maybe a different problem).  When it is working this camera have an amazing look but as I said before this solution creates new problems. Firmware upgrades have addressed the issues though, but I do not know in what extent. The smear artifact cannot be eliminated.

  2. If the Ikonoskop has a CCD sensor does that represent the return of the vertical light smearing? Or have CCDs evolved and gotten rid of that artifact?

     

     

         Yes It does have it, CCD's still the same: http://vimeo.com/40387639

     

    At 0.53 you have a big smearing. The thing with this camera is that as far as I remember, It is not 1 sensor but 4, each next to the other forming 1 big sensor. Each sensor is called quadrant and have its own operational conditions, as temperature, artifacts, etc, which cause singular problems for this solution.  If I got something wrong please correct me.

  3. Finnaly!!! Global shutter!!!! Now, to wait for cheaper cameras with it.

    Based on what? On paper (and judging by the F65 footage), the Sony F55 will beat RED on DR, low light, colour rendition, will have a higher native ISO, high FPS, better codec choices [b]and has a CCD sensor.[/b] The only tick RED has left is 5K output and the F65 just trumped that with 8K.

    Sony are currently ahead of RED in every aspect, with the excepetion of personal choice aspects, eg, ergonomics, customer service etc and possibly price, when the dust settles.

    From where you get that it's a CCD sensor? If it was, then there will be no big news: the thing is that finnaly someone comes with a CMOS with global shutter for this types of cameras (there are already but for other uses). Even Andrew put it in the article.
  4. Hello. For the ones that missed this:
