What's funny is I was about to come back here to write something like this, due to a realization I think I had just now while responding to a similar thread on another forum.
So I think it goes like this, simple example:
Say I have a perfect head and shoulders shot in my frame. Setup is a 50mm, with adapter, on my M50.
I change the adapter to a speed booster. Now instead of standing 10' away to get this ideal framing, I only need to stand 6' away. But due to getting closer the effective distortion has changed.
This leads me to wonder if deep zoom from a far distance is some ideal for portraiture... but that certainly can't be the case because I'm sure you can flatten things too much, plus you never see photographers taking portraits from 50' away .
Yes, 50' is too much, but 15-20 feet with a long lens can work. It will not flatten too much, but it is difficult to communicate with your subject if you are too far away. The EF 70-200mm f/2.8 is a VERY popular portrait lens for a reason.

Right, and I was also going to say it seems like what we (noobs that is ) are suffering from is the fact that full frame was such a prevalent thing for so long that focal lengths *for that sensor* became so ingrained/understood to be certain AOVs that that became the standard.
The king is dead, long live AOV?

"The EF 70-200mm f/2.8 is a VERY popular portrait lens for a reason."
Although 70mm end might work on the M50, the FL going up from there would be out of, to very much out of, our sweet spot AOV. There isn't a zoom in that FL for a M50 that I know of. Sigma used to make 50-150mm zoom that was close but I believe it has been discontinued.
The 70-200mm zoom is a favorite of the full frame guys.

Just think the 4/3 guys have to use 12mm to 17mm to get the same perspective. As sensor size shrinks the ability to get wide to super and ultra wide AOV becomes impossible. That is a place where a larger sensor can be a benefit. However, the 4/3 guys get a free kick on the tele end as that becomes much easier to achieve.

Shooting portraits is definitely not an area of photography I aspire to enter but one of the multiple sports students asked me to shoot some senior photos and because he wanted a lot of action shots in the mix I agreed to do so. I used more traditional portrait lenses for most of the posed photos but I brought the EF 200 f2 along because it can create beautiful sports images at the right distance.
For fun I tried a few posed shots using the EF 200 on a 5DS R body and it does have its applications. Because of gale force winds destroying the tree leaves part of Fall color earlier in the week, the best Fall color left was a clump of colorful weeds. The EF 200 nearly wide open nicely turned the weeds into a colorful blur, I wish I could so easily make them not a problem when they pop up in the gardens throughout the year.
Fortunately full sports will be returning in the future so that I won't be cursing the portrait world with my work. I am much more comfortable and have MUCH more fun with action shooting. I do enjoy reading about those who do this work on this Canon forum site but I plan to remain safely inside my action photography comfort bubble. I will be spending some quality time with Photoshop fine tuning some of these images tomorrow.

ebiggs, something interesting occurred to me during this back-and-forth; I realized that my partner and I really chanced upon something ideal, and it was quite fortuitous. See, we knew all about the vaunted nifty and thought it was the perfect way to get started in all this.
Well, what we *didn't* know about, at all, at purchase was the sensor scaling. Point being, we were getting an 80mm lens (ok, I know, here I go again using full frame-biased speech , but you know what I mean) and the results, as said, have been nothing short of astounding. Truly, it almost feels unfair how well these come out, and I curse myself when I deviate from 50/1.8 during these shoots.
But we haven't been shooting 50! I got to experience 50 yesterday when I slapped on that big EF 32 f.14 as far as I understand it, and as I said, the results sucked by comparison.
So we fortuitously stumbled into the ideal 20-30 deg AOV range for our portrait work.
Thanks small little sensor!

"(ok, I know, here I go again using full frame-biased speech ..."
Unfortunately this will be with us for ever. It seems it has become ingrained into photo-speech. The more correct, incorrect term is "crop factor". Most will not understand what you are talking about if you use the word "scaling".
Funny, too, most new shooters (I have taught DSLR 101 classes) today have never use a 35mm camera and have no reason the compare FL to it. Most just realize their 18-55mm kit zoom is good for general purpose. They never think, oh I have a 28-85mm equivalent lens.
In fact you never hear the Medium format guys refer to their cameras as "enlargement factor" cameras. They certainly qualify since they have the oppisite effect.
