Summilux 35mm 1.4 ASPH FLE aperture question

I have a question for people who have this lens. My aperture ring turns beyond 1.4 when I turn it, there is an extra small stop. This extra small stop continues to open the blades. Now, I suspect that there are three possibilities here:

- This is a defect and my 1.4 marking is not really 1.4

- I have a secret 1.3 setting

- This is normal and the two small stops are equal

Do other people who own this lens have this too?

I would go for option 3 - I have other lenses that behave similarly

I moved this thread into the lenses forum, but I am not sure how to delete it from here.

I don't own this lens anymore, but I remember it behaved exactly the same way.

You're very lucky as you have a super rare f/1.39 lens .  (you don't)

My 35 summicron asph does this to the same degree.  My 35 summilux asph pre-fle does it to a lesser degree.  I have a few other lenses that do this.  It's a trait common to many modern Leica lenses.

Also, I take the precaution of rotating the aperture ring with 2 fingers to prevent future looseness.  I suspect one finger rotation leads to this.

I remember vaguely, that there was a thread about this already. You could try to measure it by yourself, if it makes a notable difference.

My lens behaves the same way.

Indeed, seems rather normal - my Noctilux 0.95 behaves in the same way. Best, GN

Thank you all!
