Back in th film days there were several companies manifacturing film, now we will have several companies producing the chips. I wonder when they will become standirtized so we can swap them (if needed). I can't beleive Kodak let that bone go.
Sony like to be dominant player...
Joju, I meant only the major one... I remember in the 90s the refrigerators behind the counter, they were stuffed with Kodak and Fuji, and here and there Agfa and Konica. I am sure there were meny other brands.
@borisbg when I replied to you I first thought there were less sensor producers. And maybe there are, it was difficult to google the manufacturers of those different chips. As in film times, there were much more brands than producers of those films. But the producers delivered a couple of different film types and I'm nearly sure there are not much of dedicated orthochromatic monochrome sensors, or infrared. And panchromatic monochrome sensors I only know of two (PhaseOne and Leica) camera makers offering them.
Toshiba has their own sensors and own sensor designs. They have only ever designed small format sensors i.e less than 1" type. ANything bigger is simply contract manufacturing.
Just saw on canonrumors, they have reposted the press releases from canonwatch. In reading through them, I'm intrigued by a phrase. "Low-pass cancellation filter" is the R's differentiator. It doesn't say no low pass filter, or lower strength low pass filter. It says low pass cancellation filter. Now what is one of those? I presume it is optical, because if it was done in software they wouldn't need the two bodies.

They use bifringent plates the same way any other anti-low pass filter works; a binfringent material creates a vertical blur, then the light goes through the IR filter, then another bifringent material is used that is opposite to the first one, thusly "bringing it all back together." In a normal OLPF they use a bifringent material, then a 1/4 wave or 1/2 wave plate to bring the light back into phase, then another bifringent material rotated 90deg to get a "perfect" blur.
