What would the FFF have to do in order to be competative?

Reading a recent post that included a 60M pixel Bayer sensor shot, the the discussion turned into a debate as to whether the FFF would ever arrive.

Looking at the Bayer photo what do you believe the FFF sensor would have to do better than the current generation of Bayer sensors? What are the design criteria the FFF design team have?

We don't know.

I don't know but given the physics of the design and the past Foveons, low light performance would most likely not be on par with the Bayer, agreed?

Agreed.

Historically, Sigmas have required extensive image processing both while taking the shot and afterwords (SPP).

Ummm . . . my Quattro made great OOC jpegs, so no . . . not afterwards - no more than CFA cameras require extensive image processing afterwards.

Will the FFF shoot at the frame rates of the current Bayers?

Probably not.

Again, given the history, this seems doubtful.

So with low light and speed out of the equation, whats left, detail and color rendition.

I'm very interested to see how the detail capture works out, when compared to Sigma's fp L . . . and I'm sure Sigma, being the company that makes the highest-resolution L mount camera, is well aware of the challenges the FFF faces.

As for detail, how would the specs of the proposed FFF stack up against the 60M plus Bayer sensors?

How do the 45 MP Bayer cameras stack up against the 60 MP plus Bayer sensors? Those cameras still sell, even though the Sony cameras outresolve them. Some people don't need or want more than 20 MP, believe it or not.

Would the advantage in detail make up for the shortcoming?

The remaining design criteria, is color. Would Sigma's color rendition be enough for people to buy it?

For some people, yes.

I don't know and would like rational, opinions as just what will the FFF bring to the table, and why any non L mount people in 2023 would buy it when 100M pixel Bayers are on the horizon that take great low light picture at high frame rates.

Where on the horizon? Sony just rehashed their 60 MP sensor into a new A7r V body. My guess is that they might create a stacked version of that sensor at some point, so they can make a camera that can do 8Kp60 video, but 60 MP is not 100 MP. Neither Nikon or Canon have stepped up past 45 MP to match Sony's 60 MP.

And the geometric resolution of 60MP is only 15% more than 45MP ...

Well, I don't know what "geometric resolution" is Ted, but it really doesn't seem to me like there are a whole lot of people interested in more resolution than what the 60 MP Sony and Sigma cameras offer. Nikon and Canon don't seem to think there's much of a market there. I beg to differ. I believe wholeheartedly in my proposed future  "quatrification" of the 20 MP per layer FFF sensor, making a full-frame Quattro sensor that would have an 80 MP top layer. I think an L mount camera with such a sensor would make the ultimate Quattro camera, and I'm hoping it has IBIS, a fully-articulating rear screen, Wi-Fi, GPS, and can do 8Kp60 video too.
