All he has to do is travel towards the subject at a speed sufficiently
high to shift the IR into the visible part of the spectrum.

He will need to use a high shutter speed.


Focusing with a mirrorless is like focusing a view camera using the
ground glass since the AF sensors are embedded in the capture one. The
same goes for MF shooting too, of course since that what you see
through the EVF or Lieve View is that that is captured by the sensor.
C'mon, you know better than trying to support Dense Dave on this...


I hadn't followed this to the point where I had picked up that it was
a mirrorless camera.


The EOS M series are mirrorless. I have an original M, Dense Dave has a
M3 and Davoud a M5, for example.... In live view it's strictly WYSIWYG.
The light level geting to the sensor is too low for AF though while
using the gap between the IR cut of filter in camera and the screw on
one that cuts of visible light, 760nm in my case.
A converted camera should be able to use AF, if the conversion can be
done without damaging it, I e double pixel AF sensors. The live view,
in any camera will make the rear pannel, or EVF to work like ground
glass and thus correctly show actual focus.
