To better specify focus aids, as these encompass more than just focus confirmation.
Manual focus subject/face/eye detection also works with non-CPU lenses.
Magnification also zooms directly onto the subject/face/eye when it is detected.
So there are no differences between chipped and non-CPU vintage lenses regarding mf subject detection, except for focus confirmation, which requires chipped lenses or certain smart adapter solutions.
The magnification modes and focus peaking also work the same way with non CPU.
Only focusing aid which remains inactive with non-CPU/dumb adapter solutions, is the focus confirmation via green frame, green dot.
This is what it looks like when MF subject detection has found an eye.
The focus box frame remains red when not CPU-controlled, as in this case with a Thypoch Simera.
