Anyway here's the translation: "I recently got a chrome Leitz (sic) Summicron M 35/2 Asph. As you can see from the attached picture, the depth-of-field scale starts at F = 1.4, albeit the max aperture is F2.0.They made a mistake while assembling = the lens? What can I do?" Answer: "Nothing wrong in your lens:as central refer index, instead of a simple bar (=3D zero depth-of-field), has been engraved a number not related = to the max aperture, just for filling the scale" My good friend and celebrated M Superfan Guido Ridoli told me he has both lenses and they clearly made a mistake assembling that lens:in his S'lux the central point's engraved with 1.4, while the S'cron has 2.0. My comments:the usual lack of quality control we already know? The = Asian crisis?
