Yeah I'd say much of the time, not too much. But there are those sometimes, and sometimes people (even myself) want to misinterpret depending on mood, or what we WANT to believe...regardless of facts or what we've forgotten. So I think there's some of both.

Absolutely. But when it comes to "f/2 = f/2" vs "f/2 on mFT is equivalent to f/4 on FF", well, it's more one than the other, is it not?

Well it'd been a long time since I had needed, or thought of how f numbers were figured. So I remembered about the aperture and FL relationship.. no argument there. (That was one of those instances where thinking was painful on my part

I also remembered that back when I used to be involved a little in radio (not commercial) that a full wave antenna would have a much better (if the same exact design) SNR than a 1/4 wave if the signal strength were the same. So total amount of light does matter in that regard.
