    The second... Though what I'm really saying is that for anamorphic you'd crop the sides but increase the height to 18mm, so the net amount of data may be similar to going the other way, shooting...

    You bring up a good point, which is that even though the increase to 18mm would make the total pixel count larger, most people aren't going to record the full aperture anyway, they'd either record...

    I would assume that it's the total amount of data coming off of the sensor that affects the processing capabilities. With the current Dragon sensor, you can increase the max frame rates when you...

    It wouldn't be a modification it would be an entirely new sensor development and construction if you are talking about changing the size of the photosites. You'd be starting from scratch, just as...

    It's basic math -- if you keep the 8192 pixel dimension horizontally and you make the sensor shape 1.20 : 1, then the vertical has to become 6827 pixels, so the total megapixel count becomes 55.93MP....

    You can't have it both ways, if you go to the 18mm height but keep the 8K width, then your total megapixel count will end up higher than 35.4MP with the current Helium sensor photosite size.

    Depends on what you mean by loss of resolution "for other purposes"...

    Yes, you can get to 35.4MP by cutting the sensor in a different shape -- you could cut it to 26 x 18mm (1.45 : 1 shape) and...

    You'd have to trim to more than 7K...

    I did some math... If the Helium sensor is 29.9 X 15.77mm and is 8192 X 4320, then to cut it the 4-perf 35mm anamorphic dimensions of 21 X 17.5mm, you'd end...

    S35 is a physical size, 8K is a measure of horizontal pixels, and 1.90 : 1 is an aspect ratio, so it doesn't make sense to say that "8K 1.90 is larger than S35 anyway."

    Oh... I guess you are...

    You can already use Cooke and other 2X anamorphic lenses on current Dragon cameras and on the Helium cameras, it's just that with a sensor that is 1.9 : 1, not 1.2 : 1, you have to crop the sides of...

    There is a 4-stop difference between a 100mm spherical and a 50mm spherical if the 50mm spherical is set to half the distance in order to keep the same image size -- but only when you are talking...
