Leitz Hektor 13.5cm f4.5 brand_Schneider-Kreuznach This is a high qualityThe Leitz Hektor 13. 5cm f4. 5 lens might not be the highest profile lens in the Leica catalogue, but it's still a pretty decent short telephoto lens. This is a post war, black paint lens made in 1946, and it's in rough cosmetic condition: there's brassing, paint wear, and green surface corrosion. The green is easy enough to remove, but it kind of looks cool, so we've left it on. Optics are pretty decent for a lens of this age, with minor coating wear
