The lenses on the Ein Stuck have 2 concave elements. I have established that on 3 samples. I was not an LHSA member at the time of the VF article you noted. I can not refer to any other characteristic of the lens than that I have noted to discriminate differences. However, I assure you, the lenses noted use concave F+R elements. Everyone seems to want to say that these lenses were NOT the rare versions, but apparently there are only 2 versions of the 35 F1.4 aspheric lens... the Aspherical with 2 concave elements, and the ASPH with 1 concave element. Repeating the first sentence, above, my conclusion is that the Ein Stuick lenses, at least on the samples noted, using F+R concave optical elements, are the rarer Aspherical lenses. Now the help......Are you saying there is a third version with concave F+R elements, but is an ASPH version? How is that lens different from the other 2, noting we are talking about optical design and physical properties, and to a much different degree, although important, the markings on the lens? If you will be kind enough to answer, I will check the 2 samples I have access to. Maybe we can definitively put this discussion to bed.
