Gone right over yuor head hasn;t it, why do they but IR markings on lenes and
this gose back well before mirrorless are yuo really climing that IR light
focussess differntly for mirrorless cameras ?

Yes.

Mirrorless cameras have the ability to AF IR light without focusing issues
found in DSLRs. Typically with IR converted DSLRs camera/lens combos have to
be calibrated, not so with mirrorless.

With mirrorless cameras AF happens via the sensor, and you get a realtime
preview of the image before capture in either the EVF and on LCD.

Here is one photographer's experience.
