None of that is at all surprising. They used existing/old technology and therefore have all of the limitations of their current camera systems now present in their brand new mirrorless.
I know many people will defend anything Canon does, but there is no question that Canon offers much less for the money vs. their competitors. And with the EOS R, they have clearly committed to continuing this.
I've only ever used Canon. I like my Canon cameras. But I also like the benefits of new technology and forward thinking. I unfortunately have to take a loss on my glass collection as I transition to a competing brand. EOS R is not a bad camera, it's just not a great camera. And at it's price point, it offers poor value. :/
No forward thinking at Canon? Really? These may not ALL be Canon inventions but:
air sphere coatings
fluorine coatings
blue spectrum refractive optics
UD glass, Super UD glass
sub-wavelength structure coating
an 11-24 mm zoom
A fish-eye zoom lens!!!
A 28-70 f2.0 for crying out loud!!!
What are you looking for? IBIS? Is that it? They put 5 stops of IS in lenses and that ain't enough? Sure they don't ALL do that, but for every omission of great ILIS they offer a version WITH.
Sorry to un-load on you, nothing personal, but I read ad nauseam the mass perception that Canon is just sitting on their hands, raking in the cash with no regard for their customers. I use their cameras to make my living because there is NO ONE ELSE making what I need (excellent TS lenses) and backing their dependable-like-no-one-else's technology with the very best support. I shudder to think what I'd do if Canon abandoned rock-solid usable hardware to chase after every techno-feature the blog-o-sphere fancies this week.
Rant over. Apologies in advance.
