But that doesn't make it a logical progression to think that a Canon lens, driven through a Canon adapter, by a Canon camera, all of which was engineered by one department specifically to work together, is going to have the same problem. ....
All this sounds good, but I'd suggest that you only inferred the most important part, a part which we may as well spell out more clearly here in this thread, that part being;
The EOS R was also designed by that same dept. in that same company SPECIFICALLY to work with the existing lenses the same company has been making since the 1980's.
Canon new/knows going in that EF Lens compatibility was a major aspect of their mirrorless entries selling point.
I'd argue that it is in fact a "Make or Break" aspect.
As a primarily Canon shooter, the ONLY reason I am still reading about this body and considering it or it's next sibling, (vs. some fo the more refined advanced mirrorless brands) is the NATIVE functionality with my existing EF lenses.
If Mike is correct that we have to worry about this one aspect of the RF system,. then Canon has failed completely right out of the gate and there is no hope for RF.
I can make fun of Canon all day for dozens of various reasons, but I can't imagine that they would let this thing out on the streets set up to fail so completely because of incompatibility with it's own lenses.
That just reads like SciFi hysteria to me.
To compare, in the case of SONY body + Canon, Nikon, Tamron, or whatever lens, + Metabones adapter, ONLY the Jr. partner here, Metabones, set out to make the lens and body work together. Sony didn't. Tamron didn't. Canon for that matter actually tried to prevent it working to some degree. So yes again, the two cases or totally incomparable.
