Oh please, oh please be a 26mm f/2 IS STM or a 15mm f/2.4 STM!

Why? There is already a 22 f2 which I own and which is really great. What would a 26 f2 deliver?

IS.

only lens really missing in EF-M lineup today is a compact, moderately fast short tele-prime.
EF-M 85/2.4 IS STM ... with IQ like the EF-M 22/2.0 and size like EF-M 18-55 ... here we come!  8)

I have a 1Dx Mark II and a G7x. I recently went on vacation and I wanted something in between those to take with me. I figured since I already have an EF-M 18-55 I might as well just get the M6 body only and slap the 18-55 on it.

I haven't used the 18-55 mm since I got my G9 X. I see it offering nothing extra. Even the use of 22 mm has  been pretty rare. I mainly use 11-22 mm and 55-200 mm and 50 mm. They offer significant extra.

But would such a lens be any smaller than the EF one?

My guess is a 35mm f/2 lens.

compared to a full-frame 85/1.8 ... a slower, APS-C only 85/2.4 (or 2.8  ) should offer some potential for smaller size, yes. Beyond that focal length, diameter of front element [to achieve needed size of entrance pupil] will become the determining factor for size (and weight) however. But a sweet, little 85 might just be doable. :-)

Well, some of us think so.  Likely, somewhat smaller than the EF 85mm 1.8.  Certainly, a lot smaller and lighter than the new 85mm f1.4 IS, if it ever sees the light of day.

i guess (!) an EF-M 85/2.4 IS STM could be done in about the same form factor as the EF-M 18-55, and definitely shorter than the 18-150.

Maybe it's the EFM version of the G1X Mark III's 15-45 f/2.8-5.6, which hopefully replaces the existing efm 15-45 f/3.5-5.6.
Why? For about half a stop only in the wide side of the zoom?

For the LOVE of all that is holy, please make a fast zoom or prime. I would prefer a fast zoom to replace the 15-45 I have. It's a good lens for what I use it for, but having more light gathering ability and increased size isn't entirely a bad thing - look at the Fuji 18-55mm f/2.8-4 for APS-C, it's not too large and bulky.

Without being overly spiritual, I'd like to reiterate my request for a EF-M 32 f/1.8 IS and a EF-M 15-45 f/4 IS.

The new prime is going to be an EF-M 28mm f/2.8 IS STM.  No doubt.  How do I know?  Because I recently purchased the EF 28mm f/2.8 IS USM to use with my M5 and the adapter.  Why?  Because I wanted a moderately fast walk around lens that was closer to a "normal" focal length (I do have the EF-M 22mm but find it too wide for walking around on vacation, etc., which is where I use the M5 the most).  Why didn't I get the 35mm?  Because Canon refurb was out.  Why didn't I get the EF-M 28mm macro?  Because 2.8 is faster and if I'm going to do macro/closeup I'll use my 5DIV and 100 macro or extension tubes.  By the way, the EF 28mm is a little heavy on the M5 but gives me way better snaps than the 18-55.  I have also used the "new" 50mm f/1.8 with the adapter and like the results with it fairly well, but again a little long for walkaround.
5D4; 6D (for now); M5; M3 (for now); several lenses (Ls, non-Ls and Ms).  Enthusiast.

I feel like 50s are where APS-C mirrorless still has some skin in the game to keep things physically short, but crop mirrorless 85 is beginning to get into the inflection point where you are no longer saving space.

I'm not saying there's no point to offering a dedicated crop mirrorless 85 over an adapted one, but I think you'd need to dramatically slow the lens down to keep the size reduction attractive.  Barrel diameter can certainly be kept smaller with a crop only lens, but I'm not certain you'll save much length over an adapted 85 FF lens here.

Pics below of something 50-60ish vs. something 85/90-ish Fuji / EOS M vs an SL2 with a FF 85 lens.  (Sorry I couldn't drop an EF 85 f/1.8 USM in there, but the website tool had neither that nor the same-sized EF 100 f/2 USM.)

misleading image A ... adapted 50/1.8 STM is no suitable comparison.
also beats me, why camerasize.com does not include EF 85/1.8 or 100/2.0 ... but - very compact for a FF lens - EF 85/1.8 lens is physically about 50% longer than EF 50/1.4. with adapter it would be way bigger than an EF-M 18-55 sized native EF_M 85/2.4 IS STM ... or if no can do for "innovative Canon" ... at worst I'd also take a 85/2.8 IS STM.

No bias at work here, I'm just making do.  I chose the 50 STM because no 50 prime exists for EF-M at that site.

My point being: no one seems to offer a compact 85-ish lens in dedicated crop mirrorless that I am aware of as it appears that it will not be a shorter lens than a compact 85 FF lens on an adapter, and the decision to make it crop-only would waive off any FF users from buying one.  So it's possible the various camera/lens manufacturers see a 50 prime as working in a crop-only footprint, but they'll just leave 85s in a FF variant.

The only company that made their own was Fuji -- and they don't have FF business to fret over.

Could Canon make a compact EF-M 85?  Sure.  But it might be f/2.8 (as you have gathered) to be attractively small.

I think that's because Canon were cheap SOBs when they made it -- it's an 85mm lens tucked into a 100mm body.  See pic from TDP:  it's virtually the same outer barrel and size as the 100 f/2, presumably done to save cost.
