Maybe you're right, I do think it's all about high prices. I do also think they lost some M5 sales, due to people buying the CL. Maybe they learned a tough marketing lesson. Personally I've never wanted a CL, although I've handled them, mostly at camera shows.
I buy user-grade Leitz cameras and lenses, often at bargain prices, based on what I see advertised all over. I really was happy to get my chrome M5 for $510, and it's even got a name engraved (kind of cool), lots of rubs and a few teeny dings. But if it was perfect, I'd be afraid to throw it in my day bag, and use it. Prices seem to be going up. If I could find another chrome M5 for $510, I'd buy it right now.
