Wow, power move by Canon to turn the 100-400 into its own competitor to the 150-600mm lenses. Wouldn't be surprised if it's still 5.6 at 400mm and they just simply extended the range to 500mm 7.1. Pretty excellent considering how much I use a 1.4x to get a 560mm f/8, now gets you to 700mm with a 1.4x.

1000mm f/14 on a 45MP sensor, don't think the RF design will make that usable. Wonder how 500mm on this RF zoom lens would compare to EF 500 f/4?

I wouldn't use a 2x with that lens. But the 2x with the RF 70-200 2.8 is quite a sensible option

Unfortunately I'm pretty certain they're referring to the image.canon cloud for an April launch.

As few details as we got from this development announcement, Kudos to Craig for digging up as much as he has thus far. Canon does NOT make that easy to do and given their frustration over the fact that he got them... They are probably going to make things more difficult in the future

Any idea on the size of this lens. I get the feeling canon may have sacrificed a little on the apature to produce a VERY small but useful travel wildlife lens. I dont know about the rest of you but every gram and cm matters to me when i am packing for a trip to a wildlife destination

Lots of discussion in the big R5 announcement thread.
Smart money is that this is simply a 100-400 f4-5.6 that tosses in the bonus feature of pulling that front end a hair more to reach 500mm. Should be the same quality as the current, enhanced as RF enables, with a bit of a stretch on the long end for when conditions permit.
$1999?

The wording in the IBIS section makes it seem that IBIS will only work with RF IS lenses and non-IS lenses, with EF IS lenses it will be likely disabled. If that's the case, add $300 or so to the price.

I wouldn't assume that a TC will work with the lens, I'd hope so, but if it uses similar tech to the 70-300mm 4.5-5.6 L to get a more compact lens, the moving rear focus group precludes a TC.
I wonder?

As long as IBIS works with non-IS lenses like my Questar 700mm f8 mirror lenses, I'm OK. And for the non-IS 11-24, etc.
But it may be a tech challenge to get two IS systems to work together and not fight each other when one is a legacy system.

You're right, from the images of the RF teleconverters they clearly won't work with the RF 70-200. The big question is how they'll work with EF lenses and EF-RF adaptors.

Not just the images, have a look at https://www.canon.co.uk/lenses/rf-70-200mm-f2-8l-is-usm-lens/specifications/ and scroll down to "Extender Compatibility".
