Originally posted by clackers True, but from a viability of the company position, even Canon want you to buy the new lenses for the new camera, not reuse old ones. They are real desperate for cash, just like Pentax, just the number of zeroes at the end is different!
I'm not sure that you can even get their existing M series mirrorless lenses (which are also entirely electronic for focus and aperture) working on their new R series mirrorless cameras, it's as if they never existed!
I
believe, but do
not know, that these are defensive moves. Canon and Nikon are trying to keep their current DSLR users when they go MILC. When I went from film to digital, from a Canon EOS Elan to digital, I purchased a Rebel, because it could seamlessly use the only AF lenses {EOS lenses} I already had; the kit lens - a 18-55mm - provided the necessary wider focal length I needed to make up for the fact that my widest film lens was 28-80mm. Similarly, a current DSLR user can purchase a EOS-M or a EOS-R camera and not have to purchase any more lenses right now, making staying with Canon {or staying with Nikon} more attractive. As I mentioned earlier, I still have four EF lenses, so if I decided I just had to go APS-C MILC right now, the most cost-effective path would be for me to get a Canon EOS-M50 or M5 with an adapter for the lenses I packed away four years ago with the Elan {each of the two Rebels went to the dump when it died}.
Incidentally, when I gave up on Rebels, I came back to Pentax and purchased a K-30, because I still had my Super Program and a few lenses for it .... not AF, but being able to use them made the cost of the change less abrupt {four years later, I'm not using any of the film lenses with my KP, but I spread the purchase of new lenses over those four years}.
