Lately, multiple manufacturers have chosen not to release their most recent crop sensor AF lenses in EF-M mount.

• Rokinon/Samyang 12mm f/2.0 - XF
• Sigma 18-50mm f/2.8 - E, XF, L
• TTArtisan 27mm f/2.8 - XF
• Tamron 17-70mm f/2.8 - E, XF
• Tamron 18-300mm f/3.5-6.3 - E, XF
• Tamron 150-500mm f/5-6.7 - E, XF (compatible with full frame)
• Tokina 23mm f/1.4 - E, XF
• Tokina 33mm f/1.4 - E, XF
• Tokina 56mm f/1.4 - E, XF
• Viltrox 13mm f/1.4 - E, XF, Z
• Viltrox 85mm f/1.8 - E, XF, Z (compatible with full frame)

Besides Sigma, both Tamron and Viltrox have previously released AF lenses for the M system and would already have the engineering work of defining AF protocols finished.

on the contrary to your thesis

for $1042, being able to get the trio sigma primes

Sigma 16mm, 30mm, and 56mm f/1.4 DC DN Contemporary Lenses Kit (bhphotovideo.com)

and now for $549 being able to get the small f2.8 sigma zoom

Sigma 18-50mm f/2.8 DC DN Contemporary Lens for FUJIFILM X (bhphotovideo.com)

will imo opinion CRUSH fuji lens sales - my prediction is that they will be in dire straits financially by the end of next year

Totally disagree, as most Fuji users refuse to buy those lenses because they lack an aperture ring, which is a defining and desired feature of most Fuji lenses. Also, most Fuji users already have (or had and sold) the XF 18-55 f/2.8-4 which comes as a kit lens and includes an aperture ring and image stabilization, whereas the Sigma does not.

Rotation of the Sigma zoom ring is also in the wrong direction and the focal range is the most restrictive of any option available to the system.

With respect to the Sigma primes, the 30mm has to be the least popular because Fuji already has very popular prime options in that focal range. Sigma's 16mm, as excellent as it may be, really is too big and heavy for a lot of Fuji users with the smaller bodies.

If price is an issue, it is really hard to beat the XC 35mm f/2.0 for only $199. That lens is a lot smaller and half the weight of the Sigma. That Sigma 16mm is heavier and bigger than the Fuji 16mm f/1.4, and it is almost 3X the weight of the tiny Fuji 16mm f/2.0. Price is really the only reason to consider either of these Sigma options.

I speak from experience on all of these fronts, though Sigma's 56mm (which if I had to guess is most popular of the prime trio) as well as their tiny zoom are tempting. Initially enthusiastic for the latter, I'm now leaning back on the kit lens as the better option because of its metal construction and image stabilization. And it costs way less used or purchased as part of a kit than Sigma's new offering. Still, I think the Sigma zoom will do well, but from the feedback I've seen thus far in the Fuji forum not many are super excited about it because of Fuji's existing offerings.

Yes, there is a group who do not mind third party lenses and welcome Sigma and other manufacturers into the fold. Heck, I'm one of them... but I do think that the first choice of Fuji users will be Fuji lenses, just as Canon users prefer Canon lenses.

More lens options are always a good thing. The Sigma lenses are interesting options, but certainly not things that are all-around better than every other option available for the system. I could see a budget conscious user of the relatively cheap and stabilized X-S10 being more interested in these lenses than a higher level user of the X-T5 or X-H2S.

On EF-M mount, I only use(d) Canon lenses. ¯\_(ツ)_/¯

I think that is generally true for most systems

Some people will be so broke after they sell off their Canon kits and buy a new Fuji body they will settle for one of those Sigma lenses used from MPB ?
