But, you see - you've just underlined the problem with this phraseology - it has many different ways to interpret it. To me - a constant aperture lens - is one which stays open, regardless of WHAT you do.
If the lens stops down to f40 … it can hardly be referred to - as a "constant aperture lens" - can it, Paul?
Have you seen this article about a CONSTANT APERTURE zoom lens? (Yellow highlight mine)
