Leica L and Sony E are two smaller Mount compare to Canon and Nikon. Both are better than M Mount and Nikon F Mount for sure in term of Mount size for design flexibility. Sony E Mount is 46.1mm with 18mm flange distance, Leica l Mount is 51.6mm with 20mm flange distance, if you ratio them, they two are about the same I would assume they can handle about the same design first order with each has a little bit more flexibility in different area: L has bigger Mount to have bigger last element and E can put last element closer to sensor.
So, no wonder sigma will design lens natively work both Sony and L. However, if you pay attention to what canon have done with R Mount, you will realize it is not just market talk. They utilize their Mount size and flange distance on many design include 28-70, 50f1.2, 85f1.2 and even budget 35mm f1.8. Sorry I am on cellphone so no lens diagram included here.
I personally won’t expect any sigma lens designed for canikon in next few years given its bandwidth and all the hassle they need go through to back engineer Canikon’s AF. Even it does finally, I would say Sony E and Leica L are the one limit it’s full design potential just like Nikon F did on sigma tamron 3rd party design, especially on wide end and fast glass.
I would think that is why given 35f1.2 size and 82mm front element, it is still having huge vignettes.
I personally like this lens enough to order it (not only based on this fine review, there are also many Chinese reviews I have seen)but I have to say it is never at a time I hate this multiple Mount between system. You want certain lens, you either need wait forever or having multiple system.

This certainly proves there is no technical barrier to making an optically excellent autofocus f1.2 lens for FE mount.
Even after Sigma delivered a mirrorless 35mm "f/1.2" AF lens designed for the Sony E-mount with the top IQ and rendering, many will still insist the E-mount's diameter is not large enough for super fast wide angle lenses...
If there is a design advantage for larger diameter mounts, we will never see it from third party lens makers who would probably want to maximize their sales by using the same optical design in multiple mounts. They are pretty much stuck designing lenses for the E-mount (since it has the smallest diameter) and then adapt the design for other mounts...There is a chance Canon/Nikon will eventually produce a 35/1.2 that's better but until then...the mount size advantage marketing is not really as relevant anymore.
That(mount size advantage Canon and Nikon claim) was a speculation until I saw Canon's new designs. They are not just talk but utilize the mount, they use it fully. I am still waiting for Nikon ones, though (only 50f1.8s show that)
I never have doubt Sony can design f1.2 glass with their mount given Leica M can have lens like f.095. And we all know It is all relative as mentioned. I think Sigma CEO mentioned mount size as well in one of his interview: no surprise here, it offer flexibility but good engineer can always work things out....
I fully agree from now on, Sony E and L mount will define (or limit ) 3rd party MILC lens design.
Sigma is the company really gain my respect and I am even happy to build my system around its glass now as I trust them. I have used 85 and 135 art that I like both. 35 sigma can use a update but here is the one.
