Chipworks report says Canon and Nikon trade sensor fill-rate for video features

[bchernicoff]

"Canon and Nikon released the 1D X and D4 FF DSLRs, respectively, both of which sacrificed fill factor to add transistors serving as floating diffusion (FD) node switches. These switches add the flexibility to perform charge-domain binning for video modes."

I'm not trying to restart the flameware against video in our cameras, but I do want to say that I am very disappointed that two flagship stills cameras are sacrificing stills performance for video.

Not like they run a cinema line at all.... why should they compromise a flagship stills camera for video?

We are going to see more sensors redesigned for video, Canon has a patent to solve the issue by placing the circuitry on the rear of the sensor thus making for larger photosites. If that patent happens, everyone will win.

I doubt it makes much practical difference with the relatively large 1DX photosites though and the video feature is pretty awesome.

What was interesting was that so and so and so and so and so and so were doing this innovation and that trick and every body under the sun was mentioned.... other than Canon.

sony have already this sensors=stacked

From what I've been able to find, its not the same problem or solution. Canons patent has to do with the ground plane and its intended for large camera sensors. That's a limiting factor in video, frame rates are limited by the inability to have good grounds so the sensor can be erased .

Sony's stacked solution is currently used for cell phone technology.

yes it is, and it is from the phone industry new developments come from and will be translated to larger sensors

That can only be good, its something to look forward to.

well you reduce the fill factor with at least 15% if I remember correct and the fil factor is already small in a cmos , 30% of the surface

I suppose that's why there is an array of gapless microlenses over the photosites...
