Visit Mamiya then select Rangefinder, and go to Universal lenses.

According to that site the filter is a 72mm.

Thank you for your help Dave,
I found informations on the Mamiya site but not for this particular lens. I got the information on a french site it's 43mm.

I was close then?

Yes Dave you were close to the right measure !
Really it's curious it's the only lens for wich Mamiya do not indicate the size of the filter thread. It's important for me because I mostly shoot in B&W and sometimes I need a yellow or orange filter.
Have a good day
