The convenience of mirrorless with no reduction in image quality really made this change basically inevitable. But there is something rather sad for me about this eventually spelling the end of the EF lens line. There was something really magical about being able to use any EF lens on pretty any Canon SLR camera body, even going back to 1987 for either the lens or the camera, with at most a reduction in the automatic feature set. You could get an old hand-me-down and mix-and-match with the newest equipment and keep using it. (There was also the dark side of this, where Canon intentionally kept the electronic connection proprietary to make it more difficult for third-party lens makers to compete) You can still use lens adapters, but nothing quite beats the psychological satisfaction of picking up a 30-year-old lens and sticking it on a brand-new dSLR with no modifications required at all, or taking a modern lens and sticking it on an old-school film SLR.
