You missed my point.
Back then, the prices for lenses, considering inflation, weren’t too much cheaper than lenses today. My 9 cost a bit, and as I said, I was ticked at the time. So my thoughts were pretty much the same as some now. But at least EF lenses will work on the new cameras, so people now don't have the same reason to be ticked as we were then, when we couldn’t use any of our lenses. It’s hard to feel sorry for people who are mad because they bought a new EF lens, since it will work without a problem with a pretty cheap adapter, and even gain features with the control wheel adapter, or the filter adapter.
And as I also said, it will likely be 10 years before the EF mount will be gone, and even then, those lenses will still work on your new R mount camera. What I find amusing is the people who claim that because there is one lens that they say Canon must make but hasn't, they will sell off their entire Canon system and move to another maker. So selling off thousands of $ worth of lenses and spending thousands of $ in totally new equipment because of one lens, or because they think their new EF lens is now suddenly obsolete. Yes, I find that amusing. And when they move to that new system, and find that they lens they want isn’t exactly what they thought, are they going to move somewhere else?
