    Berthiot Stellor 210 / F4

    I have this lens in a serie 1b No. 6 - and found very little info about this lens

    Do any of you have info about this lens - is it Petzval or other construction

    Thanks for any help given

    Claus

    Claus, VM mentions a triplet series 1 200mm at F3.5 so perhaps series 1b is a compromise at F.4.
