Equivalence is not a complicated subject. The vast majority of photographers understand it perfectly well. And to have a prejudice against simple optical and photographic facts would be insane. It is when self-proclaimed experts twist those facts or add contentious, or sometimes downright farcical, aspects to equivalence that the arguments start.

Exactly. E-quivalence is so simplified a concept that it is most of the time useless (for comparisons of image quality) and sometimes even downright misleading.

It starts with presumption that both larger and smaller sensors are of the same generation and the only difference is their size. It is almost never so. No current full frame sensor has a linear resolution of the 16 and 20 mpix m4/3 sensors, for example.

And I have never heard an E-argument that f/1,8 on a Canon 5D mk1 is equivalent to f/4 on a Canon 5D mk4 (or whatever the difference between their full-frame sensor is).

E-ducators don't really like to educate, they just like to argue endlessly and use e-ducation as an excuse.
