It would appear from the announcement today that Sigma has decided to support only FE and L mount for their native mirrorless lenses.
Not a big issue for Nikon Z users because at least one adapter is now available, but it could be problematic for the R mount.

Strange decision from the outside. I guess they have reasons. Any indication as to why this decision was made?
-
If by R mount it is meant Canon RF, I see no problem; if one goes the way of adapting, there are plenty EF lenses to adapt to RF - both from Canon and Sigma.
It is obvious why Sigma decided - for the time being - to focus on the Sony E mount: it has the largest user base. And the L mount goes without saying: they are partners on it.
BTW #1 - so much for the spiel that the Sony E mount is too small to allow for fast lenses.
BTW #2 - interesting Sigma fp camera. Could do well with the 45 pancake lens.

Well FE is an open mount. Perhaps they need more time to work out the AF protocols on canon/nikon.

Sonyalpharumors got today’s news right a week ago, and also has R and Z versions coming later. It makes sense to support their own new mount and the current market leader first; then the rest.
Sigma also announced some of its smaller format lenses are now coming for Canon EF-M; I cannot see them supporting that but not Canon R mount!

if you look at the speed Sigma puts out new lenses - and cameras!- it is an amazing productive factory.
At Nikon it takes years to bring some new lenses. ( where is the 0.95 lens ? introduced almost a year ago)

Probably realized people like to talk about it, but not to buy it, so they put it on the back burner.

Nobody ever said fast lenses couldn’t be developed for Sony E mount.
What was said, and what is true, is that the larger Z and RF mounts offer a lot more design freedom for lens designers. The quality of Z and RF lenses released till date seem to confirm this claim.
The decision by Sigma to design based on the E mount specs means that they have favored the cost savings resulting from commonalization over fully tapping into the potential of the L mount.

I don’t think that Nikon’s marketing has the ability to forecast with any accuracy the actual interest in Nikon products... they wouldn’t be running out of stock of successful products all the time otherwise. ;)
But a shift of priorities to other lenses such as the 70-200mm f2.8 S or fast AF primes is very possible.
They may also have had to change some aspects of the design, for example in relationship to manufacturing. I wouldn’t be surprised if the polishing technique for aspherical elements had something to do with this. Many photographers don’t like the way the oof highlights of some recent designs look as they reveal grinding marks.

Sure, nobody said... it was only mentioned the "challenge" that the narrow E mount posed to develop fast lenses.
Commonalization works for all mounts - simply take the DSLR Canon EF lenses and add a tube/extension in the back. That is what they did with the first E mount lenses.
Now, they are producing more dedicated E mount lenses, ahead of the RF and Z mount. Why? Because Sony are much more well established in the market.
