Another rarest Leica Hektor 73 1.9 LTM just like my Leica Summarex 85 1.5 LTM ( together w Thambar 90 2.2 ) should definitely be classified as three old best Leica lens . But too sad Thambar 2.2 reproduced by Leica recently! Btw , SN 235816 fell correctly in the range of 235001-236000 dated 1934. W original hood , front n back cover, and Ltm to M adaptor. In almost mint condition just little bubbles ( common given the technology in that era ) n little dust. Only made 7200 units. When use f1.9 will have soft effect like Summarex 85 1.5 but 85 better as king of softness . Down to 3.2 n after will be very sharp ! Her pros is compact as only 460g if compare w summarex 85 750g and one of the best built len indeed. And many Chinese photographers stated Leica 73mm f1.9 Hektor 作為奶界三大古典人像鏡之首!
