The Sigma 16 f1.4 and 30 f1.4 for E-mount are sharp, fast and relatively affordable.
There are many small Sony lens that are very good and small but expensive.
Bingo. I have the Sigma 16/1.4 and Sigma 60/2.8 for my A6000, love them both! I haven't checked so I could be wrong but am sure the Sigma 16 & 30 isn't available in EF-M, not sure of the Sigma 60? Am going out today to buy the Sigma 30/1.4 in E mount. These are all very good examples of affordable, fast, smallish, lightish, above average lenses not available in EF-M mount. If I'm not wrong and they aren't available in EF-M mount that suggests Sigma doesn't see the business case there.
Yes the Canon 22 is good, the 11-22 UWA zoom is good, but then what else is there ??? Much of the aftermarket is passing the EF-M mount by, even for manual focus glass but they can't seem to get onboard with E mount fast enough.
Sony also has their decent 18-135, the 16-105/4.0 zoom is decent and unique being a constant f4, the 35 and 50 1.8's are good and have OSS, the Sony 85/1.8 is fantastic and not too overpriced, the 55-210 is more or less similar to the equivalent Canon zoom, but the Sony 10-18 is overpriced, the FF Sony 28/2.0 is a lens I'd like to have but am choosing the Sigma 30 over it for cost and aperture reasons.
So with E mount I have ready access to a handful of quite nice primes for reasonable money, some zoom's that are respectable with one even offering a constant f/4.0 with the only 'penalty' being the UWA which is priced double what it should be. No adapters needed.
As a bonus what I like about Sony is when I do go FF I can use my crop lenses on the FF body, something you can't do (at least at this point) with Canon, maybe the upcoming FF mirrorless will allow it but again, this is Canon we're talking about, they'll find a way to make it impossible just to force you to upgrade.
