I don't have any answers, but I did buy a new Canon 85mm f/1.8 stm that had inconsistent focus accuracy with the official adapter. Though the 50mm f/1.8 stm I have works well.
Oh, that doesn't sound good. Up until now I was hoping that these problems would be limited to lenses from other manufacturers - (...)
I’d avoid conflating issues here. You’ll muddy the waters and then never find your way out.
For now stick to determining why your Tamron lenses are misbehaving. Have they offered any solutions yet?

I’d reiterate that I don’t think your issue lies with the adapter (and the body is proven). Take it from there...
Best of luck!

The lens is still with Tamron. I spoke with the service department yesterday and was told that the lens is within the tolerances, but they still want to try a better adjustment. Basically, however, they are aware of focus problems with the mirrorless systems of all manufacturers.
That's in line with multiple reports over the years (re: Tamron). Some folks have had great results, some poor.
I've since sold my M5 body and used the proceeds to buy a 70D with the 18-135 STM - partly because of the apparently pretty good lens included in the low price and partly because I simply want the option of micro adjustments for any problematic lenses.
Hey, I shot with that combo for 5 years.
A great camera indeed. However I actually went in the opposite direction and sold it for the M5 (and EF-M lenses). I'm now shooting the M6ii.
My 50mm f2.8 Macro sent to Sigma service is apparently also out of adjustment. I'm curious to see how it will behave after repair on the M50 and 70D.
Wish you the best there.
The Sigma 28-135 f3.8-5.6 Macro clearly gives better results on the 70D than on the M50 - without any micro adjustments. This is another reason why I wonder if the problems are not at least partly due to undisclosed or unsuccessfully reverse engineered details of the EF control protocols.
That sounds odd indeed. An outlier.
Well best of luck to you! Happy shooting with your new kit!
