Do that.
Meanwhile, I just got the bits and pieces for my CRT Nikkor-O 55/1.2. Not bad for IR as well, if you keep aperture wide open to moderately closed down f/1.2-f/5.6. Which is what one normally would do in any case.
Flowers, CRT-Nikkor IR at f/1.2, R72 filter, Nikon Z5 modified.
There is some flickering due to the excessively fast shutter speed and halogen lights. Not too bad however.
