Does the Canon EOS M5 give focus confirmation with adapted manual-focus lenses?

If I mount a fully manual lens on a Canon EOS M5 using an adapter, with no electronic communication between the lens and camera, will the camera provide any focus confirmation while I turn the focus ring? Specifically, will any AF points light up to indicate focus, and will focus peaking still work?

I own a Rokinon EF-M 12mm f/2.0 wide angle lens, manual focus only, that I use with my EOS M3 and EOS M5. (To get the M5 to even recognize the lens, I had to change a "Custom Function" to allow the shutter to be released without a lens being detected. Look in the "C.Fn II: Others" section and change "Release shutter w/o lens" to "Enable".)
At this point, the MF Peaking feature will work fine with your manual-focus lens. However, the autofocus points will not light up like you describe.

Yes for focus peaking; no for AF-point focus confirmation.
With a fully manual adapted lens on the EOS M5, you’ll need to enable the custom setting to release the shutter without a detected lens. Once that is enabled, manual-focus peaking works normally and can highlight in-focus edges.
However, the camera does not appear to provide DSLR-style focus confirmation with manual lenses. The AF points do not light up or blink to confirm focus as you turn the focus ring, and there doesn’t seem to be a setting to enable that behavior.
So in practice, with a non-electronic manual lens on the M5, rely on focus peaking (and optionally magnified live view) rather than AF-point confirmation.
