I don't see how substituting an electronic viewfinder for an optical viewfinder can possibly be viewed as a "paradigm shift." When, and if, the mirrorless shift happens it will be in Canon's best interests to make it as seamless as possible. You seem to be stuck on the idea that Canon would purposely disrupt their user base for no logical reason. I think Canon is smarter than that.These are not good analogies for those who believe that FF mirrorless will result, over time, in a paradigm shift...
Why? Regardless of whether it’s cross company or not, and a different mount on each side, the parallelism is understood. Sure Canon may have a different requirement than Sony(parallel to within .0003 versus .0002, or something), but the company fabricating something like this isn’t going to struggle with parallelism due to the geometry of what’s on the parallel faces.[a] 3rd party [Metabones et al.] cross-company mount adapters with very different mount geometries - both factors present much more risk for mis-alignment than a original Canon-to-Canon adapter.
They add error components, but if you luck out they could actually make things betterAll adaptors will add error into a system. Period!
yes. But Metabones & assorted 3rd party sh*itters: = cr*ap, poor QCWhy? Regardless of whether it’s cross company or not, and a different mount on each side, the parallelism is understood.

Yes I agree the OEM will likely have better QC if for no better reason than they have no one to point fingers at.yes. But Metabones & assorted 3rd party sh*itters: = cr*ap, poor QC
Canon = gold standard, no problems.
Again: for Canon to Canon adapter: optical bench: = maybe. real life = not relevant.
The EF mount won't be dethroned. It is one of, if not THE singular, most used lens mount in the world right now. If Canon tried to phase out the EF mount, they would have an army full of decades of EF mount users battering down their doors demanding it back. The EF mount isn't going anywhere, and it won't be going anywhere for a very, very long time. I'm a huge fan of the EF mount and the lenses that use it (and I use several brands of cameras compatible with EF lenses, as well a a variety of astro cameras that are also compatible with EF), and I expect it to be around for decades to come.If EF is dethroned by a new full-frame mirrorless mount, would you hold on to your collection of EF lenses? How long? Would you keep those "L" beauties for the rest of your life, leaving them as a legacy to posterity?
What type of performance threshold would you demand of an adapter?
Personally, as y'all know, I think Canon is delaying a FF announcement because it won't bring good news to EF owners. Canon might be waiting to see how Nikon's new mount affects Nikon customers...
But I also believe Canon will continue to service current EF lenses and any in the pipeline for another 7-10 years. So, call me chicken little, or just an EF owner interested in the question of what to do with lenses that will no longer have the great resale value we've enjoyed for many years.
Remember the M? Canon introduced it and it sold well, and they maintained the existing Rebel lineup and EF-S glass BECAUSE IT SELLS WELL!!!!!Really ... nobody posted here ...
hard to eat that crow I guess ...
