T stops.  I remember when "they" decided to make it an issue for film
cameras. It started to fall apart almost immediately.  If I recall,
not too many companies reissued lenses with T stops.   Arriflex Zeiss
lenses did it, but most of us did not rush out and sell our Angenieux
lenses so we could join the club.

After all, we were shooting Color Neg, and if we transferred to video
on Rank chains or if we were going straight to print, we had great
timers doing scene-by-scene corrections.

I was shooting with a CP16 reflex with ttl exposure meter, but I still
always took incident readings if I could.  Later, most of my docs were
with Aaton cameras, but always with Angenieux glass, so T stops were
never anything I cared about.

The article seems like it is blowing smoke.  I am not too weird-ed out
if my camera might change the iso slightly to make the picture better
. . . but then, I'm never in a position to make images that are
repeatable.
