The '?' was more because I wasn't sure if it didn't stop down even more, a 2x converter would drop a 2.8 to f/5.6. Odd that it's not doing it with the 40mm, did you notice any obvious darkening on the LCD? [if set to constant preview. not sure what that's called on Canon]
....It is very odd behaviour.
I don't know what it's called in Canonspeak but my M5 is set so that it continues to display the subject on the screen until you physically cover a sensor at the viewfinder with your eye (or finger or whatever). I would have to set things up on a tripod and check any darkening on the same subject but I want my dinner! And there's some good telly to watch later (for a change!).
