So some of these lenses have USM (ring USM i believe). Does that mean they will have full time manual focus override and no focus by wire? That would be amazing!
RIng USM = highly likely will do what you want (though there are a few FBW ring USM lenses if I recall, the 85 f/1.2L II being one of them)
Nano USM = likely won't do what you want (only two so far, and both were FBW)
But both above the above (and the old Micro USM) just get listed in the name as 'USM', so we won't know until launch.
Strong +1 on Ring USM + mechanical override. There's just something proprioceptive, tactile, etc. about it that I strongly prefer.
Well. Just woke up and all I can say is wow. This seems legit. If so what a bombshell. If all is as it seems the canon's 'Sexy solution' is a phenomonal effort of engineering and forethought. But for me the important question remains. Ergonomics. This thing could be the most highly specced camera ever seen but if it feels like a Sony I wouldn't touch it with a 10ft barge pole. And other than ergonomics I want to know what the EVF is like. I haven't had the opportunity to look at an A73 or A9 EVF but all the others I have looked through have not been sufficient.
I agree on older Sony models but I played with an A7iii recently and thought "I like the feel of this". I was switching between my 6D, an M50 and an A7iii. If you think the 6D is too small, you won't like the other two at all. The M50 was way too small for me to enjoy using for more than occasional shots (like my a6000). If I didn't own the a6000, I'd get an M50 just to have something small enough to carry almost anywhere. I don't love the size, but sometimes the smallness is needed. (Sneaking it into concerts...) I'm happy with the size of my 6D but I found the thickness increase of the A7iii (up from the the older A7ii, which I wasn't crazy about) made it feel pretty darn usable. I think I could really get used to it.
So my hope is that this new Canon is at least the size of the A7iii.
Offer a crop mode. Nikon and Sony both do. This is a fairly easy thing to implement, and now that the mirror is gone + EF is (possibly) native compatible, there's no reason not to.
If we are reading the tea leaves here incorrectly and it's a thin body + EF adaptor, then it would be thin body + EF/EF-S adaptor. Nothing mechanically would be a problem with EF-S on that adaptor if the mirror is gone.
I doubt people would buy EF-S instead of their RF counterpart (waste that much of the sensor!) BUT I will use a little EF-S pancake when wanting a stealth EOS-R for street photography (where megapixels mean naught!)But do they want customers buying cheaper EF-S lenses instead of these new R lenses? Depends on relative pricing and how generous they're feeling, I guess.
Am i completely in a different perspective? I will buy a new body ONLY because the new 28-70 F2...
I REALLY don't care about the body, if it will be between 6dmk2 and 5dmk4 sensor it will be good enough for me. The big news is the lens... it's an L lens... it's a zoom... and it's F2.0...
And still... no one is talking about this...
