>>But my point is when they built the first SP Nikon had a hundred thousand focus mounts under their belt, not less than 1000. Buying a New SP is kind of like buying a Nikon I.<<
Fred,
Nikon had just made 10,000 cameras (the S3-2000) before tackling the SP-2005. So, using your own reasoning, the SP is a very mature product off of a disciplined, experienced production line. I assume fewer people were involved in the reissues compared to 50 years ago, so that by the middle of the S3-2000, you had a very experienced top-notch production line going.
