Ok, I was being pessimistic. I agree it would be great if someone produces an EF2Z adapter with 100% functionality. In general I tend to be a little pessimistic when it comes to what will happen in the future (especially with Nikon) and you're a bit more optimistic... I think occasionally you veer toward the realm of 'fanciful'... but hey, what do I know? And I enjoy your enthusiasm!
I think we agree that probably for quite a while, if people want full AF functionality, they will be forced to use mirrorless adapters limited to Nikon-to-Nikon and Canon-to-Canon, and this is even more true for super telephotos because it may be a long wait for native versions of those big lenses.
In the near term, I am most interested to see how those first shorter S lenses perform in real use, and whether they live up to the promise of those MTF charts, which might be theoretical.

LOL :-O ..... I would prefer 'visionary' rather than 'fanciful'
- I've lived and worked ~10 years or more into the future while juggling today for ages now, and after all you're just being a realist - so all good
:-O
The perfect EF2Z adaptor while possible (and I would say desirable) in theory, would take some big corporate kahunas to bring into reality .... Metabones, a maverick start up, crowd funded enthusiasts, private equity, or lotto winners, etc ...... who knows ? :cat:
I think you will be safe with the S line lenses in real use. The Z mount has fantastic design physics advantages. The Canon R is similar, but it is now the Sony FE that seems more constrained and compromised by its dimensions going forward - despite their native lens catalogue quantity lead.
I think if I was Nikon and Canon, I'd be sitting down with the third party lens makers and opening up the new mirrorless lens mount and communication protocols and getting them to design and take full advantage of the reduced size and increased performance advantages offered by the R and Z mounts by fairly tightly framed collaborative agreements. This is something that Sony's mount design ultimately couldn't quite match - particularly at the shorter and faster focal lengths (they'd always need an extra lens pair, weight, length, and cost, for comparable performance). The only snag in that neat strategic encirclement would be that Sony's financial and shareholding tentacles extend some way into Tamron - so they'd be more unwilling to bite the hand that partially feeds it.
If the third parties design for R/Z there will be weight, size, cost advantages over Sony - who will then be somewhat locked out of future lens developments and upgrades, unless they fund those solo, which would always mean higher prices for them alone. It could mean that Sony is eventually forced to change its FF mirrorless mount dimensions and specifications with a new bigger mount more in line with the R, and Z mounts ...... keep your eyes peeled folks! And be prepared. I'd certainly carefully consider Sony investment decisions going forward. They are going to be forced to WOW us body performance wise --- just to stand still ...... that may suit some buyers in the short term ......
If however, the third parties design for the lowest common denominator (Sony with its relatively narrower longer throated lens mount design), then the Canon R and Nikon Z mount lenses will just be compromised Sony ones with empty tube extensions built in to the lens bodies at the mount end and importantly more compromised IQ than what would be otherwise possible. Less than ideal. The individual CaNikon native lenses would then always be that bit more superior (and expensive - read profitable, no doubt)
If I was Nikon I'd also be onto the blower (or golf course as they may prefer
to Panasonic and getting them to use the Z mount in their new FF for very reasonable 'mates rates' - that would further help put the competitive blow torch on Canon, but more particularly Sony.
All said the FF strategic landscape is relatively straight forward - it's in the DX arena where the road map spaghetti really gets messy ......
Chosun :gh:
