The next Foveon camera?

That Canon R5 jpeg seems to have a compression ratio of 3.7.

I have trouble finding any jpeg images from my DP2m that would have as high or higher compression ratio. The average (median) of my DP2m jpegs seem to be about 20MB, in rare cases above 25MB and once almost 30MB (via some deliberate tweaking in Sigma PhotoPro).

And visually I would still prefer a well lit scene captured by DP2m than by Canon R5, at least based on the R5 images that I have seen.

I would certainly be interested in a new Foveon successor to DP2m, especially if it were optimized for 8k (TV) screen resolution, given that it won't cost (much) more than DP2m did.

The point of my thread is to show that the competition from high-resolution Bayer sensors, in general, is getting so high against the future FF Foveon, that there is really no point in making a FF Foveon camera.

That is if Sigma is competing with Sony, Canon, Nikon, etc.

Sigma's goal was always the ultimate IQ,

As I said before, I don't know what ultimate IQ is. IQ as defined by a Sigma user seems to me to be qualitatively, not quantitatively, different than the IQ of bayer sensor cameras.

and Foveon has lost that battle against the high-resolution Bayer.

They lost the battle for market supremacy a long time ago. If Sigma wanted the foveon sensor to become the flavor used by many other camera companies, that dream has been over for a long time.

This is my feeling, I think outside a few people no one has seen such an FFF photo.

Forget those damn jpegs, it's about well-developed raw photos from high res Bayer sensors, made with excellent lenses.

And making a FF Foveon camera for a few thousand Foveon fans and lovers of this special rendering, that makes no sense, that won't get you out of development costs.

By that logic, Sigma making cameras since, let's say, 2009 makes no sense. The market share for Sigma cameras is, what, less than 1%?

Of course, I hope that the FF Foveon camera will be realised. But the longer this wait goes on, the more unlikely it becomes. This has been going on for years.

NIkon D300 owners waited for a long time for a successor to be released. Patience was rewarded.

I think Sigma is confronting the daunting challenge of actually making a working, reliable full frame foveon sensor. Scientists have proven that fusion is possible. But, it ain't going to power cars anytime soon.

Jozef.

Scientists have proved that electricity from fusion is possible; now engineers have to make it practical, which may take a while.

Likewise, Sigma have to make a practical 3-layer FF sensor. It's an engineering problem, not a scientific one.

Yes, it's an analogy meant to show the difficulty involved in not just creating a full frame foveon sensor but also of getting one to market.   There are difficulties outside of financial ones in creating a full frame foveon sensor camera and then releasing it into the market. I didn't mean to get into a literal examination of the differences between science and engineering.
