One thing I have come to understand about Cosina and Mr. Kobayashi is that I don't understand his logic. He does what he wants to. How many 35mm M-mount lenses do they make? More than Leica! Or oddball lenses? More than Leica. My guess is Kobayashi is not concerned about price-performance curves (his accountants probably are). If anything, Cosina seems to like addressing niches. The ~$2000 like-a-Leica-but-cheaper is another niche they could address.
I think the problem is once you get to that price point, people’s minds my change as to what they want. While originally they may have wanted that new $2000 Cosina lens, they may get gun shy and instead opt for a very nice used Leica lens for the same money, even if the on paper specs are not as impressive.
I’m wondering how many Zeiss ZM Distagon 35 1.4 lenses are now sold. Isn’t that lens now just over $2K?
