Do you really think CaNikon have become market leaders by nurturing their customer base? I don't. I think they advertise the s**t out of their products and keep the prices competitive by selling volume instead of quality. I don't have a source for this, but I remember reading in a book years ago that in the early 60s Nikon supplied a bunch of newspapers with free, or at cost, gear for their PJs. This is when Leica lost that market. People started seeing PJs using Nikons and assumed they must be the best, just like they did with Leicas a decade before.
If Nikon was nurturing its base they would have come out with a digital SP by now. They reissued the SP and S3, which was pretty amazing, but they then went on to cry that they lost money on it.
If Cosina was nurturing their base, they would have come out with a digital RF by now. I think Cosina does a pretty good job with most everything they do, but they have really dropped the ball on this issue. People want an affordable digital RF and they are probably the only company that can make it, and they won't. They are serving the whim of their owner, not their customers.
I think Leica is serving their customers, and the whim of their owners. Leica could have sat back for another 3 years and let the M9 peter out before introducing anything new. But they didn't, they introduced a (potentially) revolutionary camera. They also introduced a new 50mm when they could have left the lowly Summicron alone, where it would sell in its present formulation for many more years. They also introduced the Summarit line for people on a budget.
Anyway, just my .02.
