I know that a good number of us own the Voigtlander 15mm Heliar and a few have the 12mm. Does anybody here own the M mount Zeiss Hologon lens that was marketed by Leitz, or the Zeiss Hologon camera with fixed lens? At the time they were both failures on the market. I wonder if there are any snobs who won't buy the Japanese made Heliar but would gladly spend 5 or 10 times as much for a made in Solms genuine Leica 15mm lens? What are your thoughts on this?
