With Nikon and Canon going to the latest mirrorless systems. It's got me speculating what could happen in the future and how far into the future who knows. I only got into photography 15yrs ago .... When Canon went from the FD system to the EOS system in 1987 how was the mood like and how quickly or slowly did customers went over to the EOS system? Were dealers discounting new stock, I imagine back then eBay may not had existed then. What did the Canon FD owners did? Did they hold onto them and was it over time they slowly sold/given away their items? Cheers.
