41mm filters-what do they fit?

[Chuck A]

I recently purchased a set of filters that the seller said were 40mm. It turns out that they are 41mm. They are B&W filters labeled 41E in various colors. Anyway, I can't seem to find a lens that takes 41mm filters.

I have seen Leica filters in this size but am not sure what lenses take 41mm filters.

They fit the Leitz Summarit.

Which ones did you get? I'm looking for a couple.

Best,

Ray,

I'll look and let you know. I think they are orange, yellow, blue, green and haze.
