Thanks for the link to the update, Helged.

I have had a SD-14 with the Sigma lens mount replaced by a Leica R mount for many years and it works exceptionally well with my R lenses and became my 'R10' camera.  Alas it has sat on the shelf since the SL came out but it produced wonderfully 'organic' pictures that I've always found more pleasant than those taken through a Bayer matrix and interpolated/demosaiced.

I would also join the FF-Foveon queue.

+1. If getting through the Sigma-system, it will greatly expand the L-mount and, as with your 'R10', allow for almost all mount systems out there...

If it happens, I wonder what the post production workflow will be. I had DP2 and DP3 Merrill and the usual Sigma software compromises were painful, albeit nice cameras often producing amazing images.

At least I can process my FP raw in Capture One. I’m not going to pay four or five grand for a foveon Sigma that can only be processed in their own software.

Back when I had a foveon, you just had to run all your digital foveon images through a converter once; from then on, you could use the resulting DNGs. You had to apply the procedure but once to each image, if I recall correctly. It was a long time ago.

It was same with my SD-14; convert with the Sigma proprietary software that was supplied with the camera and feed into the processing package of your choice - in my case it was and still is Photoshop CS6.

Still an extra step not needed with the FP or FPL

The FP and FPL both have CMOS sensors with Bayer Matrices, which is why you can load their un-demosiaced CMOS files straight into the processing software of your choice.  CaptureOne, PS, LR etc aren't set up to read layered, additive Foveon sensor files so you won't reap the benefits of the Foveon sensor of course and the extra conversion step is needed to make that possible.  Perhaps you could bring pressure to bear on the processing companies to develop their software so it can also read Foveon layered, additive files.

Ultimately you will decide if a minute or two converting Foveon layered, additive files to benefit from the Foveon's superb colours etc is worthwhile but I certainly would feel it to be worthwhile.  YMMV.

I loaded into Sigma Photo (slow and clunky) and exported as TIFF to process in Capture One.

It is an extra step. But I run a batch file for converting them all to TIFFs (either 8 or 16-bit, depending on my mood), and then they process very, very easily in PS or LR, too.

There were several things experienced users suggested doing before exporting as TIFF from Sigma Photo.

Reduce yellows..... adjust the sharpening etc.

I tend to have one or two photos worth pursuing in every card upload, so it was a case of loading everything into Sigma Photo and just exporting the couple of images worth processing in CO.

If this can be trusted (see the confirming post on the 4th page of this--need to wade through absurd discussion of electric cars), the Foven FF L mount is very close to reality.

The link isnt working (for me), but I assume this is the message: photorumors.com/2022/04/20/update-on-the-sigma-full-frame-mirrorless-camera-with-l-mount-and-60mp-foveon-sensor-with-x3-111-technology/amp/

What happened was that there was a report (IIRC, an email) from Yamaki to a European "Sigma Ambassador" that there was progress and implied the camera was on the horizon. Then, several posters decided to debate batteries in electric cars despite pleas from the rest of us to stay on message, and the original poster then asked the mods to shut down the thread.

We do lock threads from time to time, but not just on user request. Threads are not "owned" by the original poster. I don't recall locking any thread about Foveon sensors. In general, pleas in threads are ineffective. Only reporting is sure to reach a moderator.

it’s totally contradicting Sigma latest press release about Foveon development being only at phase 2 over 3. 
Foveon full frame camera will not be ready before a couple of years. Each phase took a very long time. And phase 2 has to be conducted as many time as necessary.

How can we believe a mysterious report about Sigma CEO calling a Slovak ambassador to confirm that the camera is near ?? It is to far fetched to be true. 
So many questions. Why no press release from the most transparent photo company ? 
Why we did not have the name of the ambassador? Why Slovakia ? Why not Slovenia ? 🙃🧐🤪

It was a thread on the DPR, not here. They're a lot weirder than us. 🙂

I would like to speculate, because it is complete and utter speculation, that the very latest Leica-Panasonic alliance (sort of like the renewed over and over again alliances of oil-producing countries) that is separate from the L alliance that included Sigma is an indication that Sigma is going its own way on camera bodies. I know there is no logic here, but I am so very much hoping for a FF Foveon L mount....I just don't have the shoulders for an S system and I want to believe that the Foveon will be the closest thing in IQ.

…The L-mount offers an entry for too many lenses, that will work poor on Foveon.

Why do you think that the L-Mount lenses will work poor on that sensor?
