as so often, you are just trying to obfuscate things. Yes, adapted EF lenses will keep working - about as well as they have in live view on mirrorslappers. But they will never have enhanced performance and functionality possible with new native RF lenses. EF lenses are "legacy" on mirrorfree FF and are subject to all sorts of limitations. Which is exactly what i've said all along and got criticized for it. NOW it is "obvious". lolYou know, it isn't about EF limitations. EF continues to function like it always has. It didn't get worse. You keep implying people have blinders on. The only person around here that refuses to believe things is you.
BTW: Are you in love with those big, heavy new RF lenses like I am?
Starting RF lens lineup looks a bit weird. But at least all Canon RF lenses are AF, as opposed to the pre-announced pink unicorn Nikon 58/0.95 Noct "folly".
Personally I'd have preferred a good IQ, really compact 24-70/4 plus a few f/1.8 primes - but not as big and expensive as the Nikon Z's.
RF 35mm/1.8 - yes ok, but not much interested in "1:2 pseudo macro".
RF 50/1.2 and RF 28-70/2 pickle jars - will be interesting how many of those Canon will really sell. The air gets pretty thin at those price levels.
RF 24-105: honestly surprised Canon was not able to do better than EF Mk. II in terms of IQ and size/weight. Anyways, in typical Canon fashion they charge 30% more for it ...
In summary mixed feelings towards Canon RF system launch:
1. lens mount parameters perfectly chosen [FFD and throat width pretty much as per my earlier speculations] ... excellent!
2. EOS R body is for me on the large side and way overpriced for only 6D III specs and 2-years old sensor ... meh
3. RF lens lineup ... for amateur/enthusiasts with no unlimited budget ... also meh
My course of action: will not pre-order but sit back and see what more will come. Either a much lower price "entry level body" and/or street prices falling to "reasonable" levels. A "summer 2019 cashback" offer or firesale resulting in € 1999 for R + basic adapter + kit lens ... might get me tempted.
