I like to stick with Canon. Really wish there were a few more native lenses like a 16 1.4.
The Sigma lenses are native,
They are not "native". Just like all other Canon mount Sigma lenses, the mount and communication protocol have been reverse engineered. Sigma may have done a very good job reverse engineering the AF protocols, but they are definitely not "native". A future M system body could easily "break" compatibility with Sigma EF-M lenses and force a firmware update.
The only Sigma lenses with truly "native" protocols are those produced for the open m4/3 and Sony E mounts.
therefore you do have access to a native 16 f/1.4. Just because you refuse to acknowledge third party manufacturers, doesn't mean they don't exist. I prefer to evaluate lenses on their own merit, independent of who manufactures them.
The Tamron EF-M mount 18-200mm lens has required multiple firmware updates to maintain compatibility with newer M bodies. First the M3 broke compatibility, and then the M5/M6 broke it again. I can't remember, but there may have been a third body that broke compatibility.
I don't care of it's Panasonic or Olympus (or someone else) who is manufacturing my lens for m4/3. I have the Viltrox X 85 f/1.8 because it's better than the Fujinon 85 f/2.
Fuji does not have a 85mm f/2, so I guess the Viltrox would be better if you are comparing to a lens that does not exist.
I have a Sigma zoom for my Pentax KP because the Pentax lens (16-50 f/2.8 SDM) is (comparatively) hot garbage. Blind brand allegiance is doing you, the consumer, no favours.
The Pentax 16-50mm f/2.8 is a repackaged Tokina 16-50mm f/2.8. That "hot garbage" is a third party design.
Always the pendant. The Sigmas are functionally native at this point in time. As for the Viltrox vs Fuji comparison, it's clearly a typo and I meant to write 90 mm, but I guess being disingenuous so you can win some imaginary internet argument makes you happy.
I won't touch the Pentax argument as it's clear you are so dead set on being technically correct that you are missing the spirit of the discussion.
While the Sigmas are great, it is true that they are not native lenses for Canon. It is for Sony E mount as the lens communication protocols are open. We never know when AF incompatibility might happen. During the DSLR days, Sigmas always have issues with AF compared to using an actual native lens.
While it has been minimised due to mirrorless tech being a on sensor AF (phase detect/Dual Pixel), the risk is still there. I think when buying these lenses we should be aware that one day it might just not work with a newer body.
