Sigma fp with Foveon coming on February 25 2025?

[eatstoomuchjam]

I've been seeing a lot of buzz this morning that Sigma have a new product announcement coming on February 25 and that it'll be for a new fp model.  This unverified teaser seems to indicate that it'll be an fp body with a Foveon sensor.

Full frame?
Video capable?

Details are scant, but maybe it'll finally be time for Foveon to go mainstream!  OR, at least, a little less obscure...

IF it is true, ie, that a new Sigma, possibly Fp camera is coming and if it is also true that LUMIX are not partnering with Leica and the SL-3 61mp (which we know is actually Sony and available in several other cameras) then maybe…just maybe, LUMIX and Sigma are partnering up and this new 44mp sensor is either a Sigma developed sensor or a collab?

Now THAT might be VERY interesting…

Same dates for the 2 announcements so even more likely?

Looks real to me!

[MrSMW]

Coincidence on the date of these announcements or not though?

2 new L Mount cameras, same day, new not seen before sensor for at least one of them?

I think there might be something in this…

FP X3? Did I miss the one and two?

Yeah, could be amazing, but would it do video? I have serious doubts. Going from the Merrill series taking quite a long time to output 50 shots on one battery to a camera that can output 61MP shots anywhere in the realm of a modern camera with a Bayer sensor would be a stretch IMO. However, going back to any of the previous Foveon equipped cameras, the output was amazing and I'd love to have one.

So my gut is that it's not real, unless it's a very far-future "we have decided to begin development" kind of announcement, but just for fun...

Sigma already makes a large number of APS-C lenses. Is it far fetched that they would make an APS-C foveon fp camera? Or maybe not foveon at all, with a sensor similar to the XH2S? This is pure speculation. It just seems odd for Sigma to make a competing L-mount announcement with Panasonic, unless it's a vastly different camera, or one that won't be available for a long time.

What is the difference between foveon and regular sensors? Excuse my ignorance!

Tl;dr it captures RGB data at every photosite, instead of using a color filter array to capture RG or B at each photosite. Thus it does not require color interpolation, aka demosaicing, to reconstruct its color image. It's not as good as it sounds, however, because interpolating colors from the vertically stacked photosites is very complicated.

The upside is less color moire, higher resolution per nominal pixel count, and arguably "better" color accuracy.

The downside is that (with current technology), it has significantly lower SNR, sensitivity, and readout speeds.

Thank you!

My instinct based on absolutely nada evidence is that if Sigma do indeed announce a new camera in a couple of days, it will not be a fovean sensor.

I am ready to enter into a hat eating contest (as long as the hat is of reasonable size and relatively hygenic) if it’s not the same 44mp sensor as this new PannyBoy.

Seems too big a coincidence to me.

If that is the case, it had better have IBIS and some form of tilt screen this time or I’d stick with the LUMIX offering.

I really REALLY fancy a Sigma FP type camera but they have fallen short (well short) of my real world needs so far.

If you blinked sometime around 2002, you missed the X2.  🤣

 

Anyway, if they made a video-capable Foveon or they're using the same sensor as the basically-confirmed S1R II, it could be a really interesting camera.  But if it can still only record 8 bit internally, an 8K sensor puts it in a category where the EOS R5 is smaller once the camera is rigged up for 12-bit recording and/or with an EVF.

For me, if they released a new fp or fp-l which was exactly the same as the old one, even with the same sensor, and they enabled 12-bit internal recording at 4K, I'd grab it.  Make the PDAF work as well as Panasonic and I'd RUN to grab it.  I love the form factor - just would get bummed out that by the time I had it to record in the quality I wanted, it was substantially bigger than the R5 next to it which could also record 8K.
