Just looking at those lenses I would have guessed the one on the left was at f/11 or even f/16. The one on the right looks more like f/5.6.
That is a serious flaw tho.
I can remember back in the 70s I had a really good camera repairman. He once told me that very few camera shutters actually produced 1/1000th of a second when set on that. Typically it was more like 1/700th.
Anything over 250th are done electronically. The CCD controls the amount of light absorbed. The mechanism doesn’t have to move any faster now, and the times are digitally managed so they are consistent.

He was right. Which is why some of us used tests to determine how the camera actually worked using spotmeters and machines which would read the density of the exposure on different films. Working with film was a blast, endlessly entertaining.
