Well the statement in quotes is obviously true. There is no way that f ratio can affect the number of photons hitting and hence being transmitted by the objective. What happens after the photons are transmitted by the objective is where the disagreement arises.
Nothing wrong with robust or inflammatory discussion. Just treat it as all good fun!
