basically, I want to use eight dslr cameras and point them THROUGH THE SAME LENS. Then I will click them all in sequence so as to get a movie out of them.
How?
A small mirror is posted onto the axis of a stepper motor at a 45 degree angle. above this is a lens with the back end facing the mirror
such that the axis of the motor points to the middle of the circular glass of the lens back end. This Multiple dslr cameras (or disembodied image sensors with supporting circuitry) are situated in a circle around the mirror on the plane perpendicular to the axis of the stepper motor such that light coming into the lens is distributed to the individual cameras. Obviously, a nice, neat chassis. to illustrate, imagine sticking a bunch of inward facing cameras to the outside of a jar, and screwing a lens onto the place where the lid should go. That would be the shape, roughly. It would be hand-held.

Baked, I fear (well kind of...same principle, higher speed, lower resolution) [cowtamer, Apr 25 2009]
the link above is not even close to the same thing..this is closer, but not really

good example of the type of camera to use, there are cheaper ones

Would this idea be for silent movies? Granted, sound could be recorded separately, but I'd find the rapid clicking of the DSLR's a little distracting. |

Current digital cameras can do something like 500fps using something like your idea : the sensor is separated into many virtual sensors, that are read out in short order. Extending this idea to physically separate sensors that get the picture via moving mirrors should be baked somewhere, but admittedly i cannot find a link. whether baked or not, it is a good idea. |

My brothers new digital rebel has a mode where the shutter is not used. I'm not sure if they can all do this, or even if the fps is increased or decreased when you do. It is actually really hard to find good basic info on this. Alot of the cameras info online say they can only shoot continuously for x amount of frames, but that rating is for stock memory, according to my brother. Also, the frame rate changes based upon what iso and other settings you have the camera on. Anyways, I would love to be able to shoot a great looking movie 40 seconds at a time even. |

the difference is really all the difference in the world. that method necessarily sacrifices resolution and quality. |

-You can rent film cameras. Or buy Russian ones on eBay. I'm picturing at least a $30,000 contraption here, and it wouldn't exactly be portable. |

nope, you are way off. Go check prices on dslr cameras. While you are at it check their weights. With no lens, they weigh almost nothing. Their bodies can be stripped down too. |

Matt, you are a terminal nay-sayer. |
