Here is the Canon RF 100-400mm f/5.6-8 IS USM

That said, the Fuji 70-300 is equivalent to 106-456mm f/6-8.5, so other than perhaps a little bit of size and the addition of weather sealing and a hood included in the box, the fundamentals of this lens and the Fuji really are not very different. Which isn't to say "how dare you, you must buy Canon" or anything—I have a bunch of Fuji gear myself and there are certainly other reasons to opt for theirs over Canon—just that you might want to wait for proper in-depth reviews (not just one day's hands-on) to come out for both lenses before choosing, since at least in terms of the most important spec they're not as different as they may first seem. Especially since I see you have the R6 and R5, I can guarantee from experience that you'll get a cleaner and more detailed image shooting either of those cameras at f/8 ISO 1600 than you will shooting the X-E4 at f/5.6 ISO 800, for example. (Especially if you downsample the R5, obviously.)

I honestly feel like Canon is doing an excellent job making APS-C basically irrelevant for the RF mount. I get the sense Canon looked at APS-C, asked themselves, "what are people getting out of these crop lenses?" and is building that out in a full frame format for the low end RF mount.

When cheap focus systems could only focus to F/5.6, they had way more limits on lens design. But now that any DPAF sensor can easily focus at F/16 or even higher, they've totally taken away that limit on lens design, so instead of compromising on the sensor, you're compromising on the aperture.

It honestly makes for a far better upgrading experience, because instead of compromising on the sensor quality and needing to upgrade the body, you can upgrade the lens and get the full experience of full frame.

It almost feels like Canon is setting themselves up to be to full frame what Fuji is to APS-C. If they can release a $800 full frame that someone can grab used in two/three years for $500, I think a lot of entry level people will end up grabbing a Canon as their first camera because they're all told "full frame is better."

Nice. Too bad all my Canon gear is EF mount. Eventually I suppose I'll be switching to Fuji or Sony. Sad to see Canon essentially abandon long time EF users as the EF lens portfolio shrinks.
Canon is the ONE brand to make the new mount adaptable. You are not left out in the cold, in fact if you could see it as glass half full you could see how versatile your kit is. This has been regurgitated over and over in the past couple of years, your post is like a time machine back to those days of grumbling yore.

They have not abandoned EF users. You can still use your EF lenses on RF cameras and they work just as well.
It's unreasonable to expect Canon to keep developing the EF mount when the whole world and competition is turning mirrorless.

Meanwhile Sony has a 200-600 f/6.3 for $2k, and it's phenomenal. Internally zooming too!

Canon has absolutely nothing even close to that.

Why do we need another junky slow novelty lens? Where are all the innovative lenses Canon promised when they switched to RF mount?

Other than the 28-70 none of the RF lenses are unique.

Exactly. Why, over the past three years alone, the mirrorless portion of the ILC market has grown by an astounding 3% (from 54% to 57%). A whopping 1% per year shift from DSLR to MILC. The domination by mirrorless is clear, which is why it makes total sense for Canon to stop DSLR development.

Or…not.

RF 800mm f/11 and RF 600mm f/11 not unique?

1.4x T.C works great on my EF100-400ii with my 7Dii
Also it works over the whole zoom range not like the crippled RF100-500 + T.Cs set up!
2x works as well but only manual focus on my 7Dii , apparently works pretty ok on mirrorless and matches the 800mm f/11 of the RF800
I would just keep my EF zoom if I go mirrorless rather than buy this new RF one.

I just can't find my feet in this new RF system. This is not the lens for me. I bought the 800, f11 and yeah it's light and compact, but unusable in most situations I found out, unless I really jackup the ISO. This is kinda the same. Really wish Canon come up with something like the Sony 200-600 f6.3 not just these low end toys. People much buy them because they are cheap i suppose.
Well the excellent Sony 200-600 costs $2000 USD
Be nice if Canon decides to make a RF200-600mm DO f/4-5.6 which potentially might weigh only about 2kg but wouldn't be cheap of course

The 100-400mm II + 2x TC does not match the 800mm f/11 on the R5. The zoom is OK at 800mm, but not much more than that, while the 800mm f/11 is significantly better - I have both lenses. The 100-500mm + 2x TC at 1000mm is very good.

Man, I'm not really sure what to think about this maximum aperture at 400mm. The price seems good and the size/weight are very appealing...but this isn't as compact and tidy as I was hoping for in my head for this sacrifice in light gathering. Oh well I was waiting for price/performance...but it looks like I'm getting the Fuji XF 70-300 instead for my casual walk-around super telephoto.
Didn't know the Fuji XF 70-300 is a super telephoto :ROFLMAO:

[Five year from now;] There aren't enough medium-high grade lenses (2 on 1-5 scale)! There aren't enough medium-low grade lenses (4 on a 1-5 scale)!
I know you're joking but, I was kind of surprised to see that there were so many comments asking for a mid-range zoom when we already have the 100-500mm. A zoom that is between $700 and $2800 might be between the quality of the RF 100-400 and the 100-500, but I thought the 100-500 was the "mid-range" option given the aperture at 500mm. Surely some day there will be a higher priced options like RF 200-400 or 200-500 F4 priced in the $10,00-$12,000 ball park and that will be the eventual high end option. It would also be nice to see something a bit less expensive, but still brighter than the 100-500mm (like the 400mm DO II equivalent but for zooms).

So yeah, eventually to make everyone happy you would fill about 5 price tiers ($700 100-400, $1500 future medium-low grade zoom, $2800 100-500, $5000-7000 medium-high grade zoom, and $10000-12000 high-high grade zoom.

All your EF glass works better adapted on R cameras than it did on EF cameras and far better than if you tried to adapt them for Fuji or Sony .
The change from EF to RF mount is better than any other mount change by any manufacturer ever, every EF and EF-s lens ever made works flawlessly adapted on all the R cameras.
Not sure how you think Canon is abandoning EF users ?

Well, you do realize ( I assume) that the EF portfolio of lenses is extremely wide ranging and essentiall complete, and you can buy EF lenses covering virtually any range or speed you want for your EF mount gear. And - get this - they will work just as well if you decide to get a Canon RF mount camera. If you switch to Sony or Fuji, what exactly do you gain, whereas you will lose a lot.
