We have been told by a great source that Canon plans to announce an RF 70-400mm f/4.5-5.6L IS USM lens sometime this year.  Though we don’t exactly know when.
Back in September, we saw a patent for such an optical formula. and it makes a lot of sense that such a lens would hit the RF mount sooner than later.
The same source also said to expect it to be about the same size as the recently released Canon RF 70-200mm f/2.8L IS USM.
The image for this post is the EF 100-400mm f/4.5-5.6L IS II USM

Suggesting it might be about the same size as the RF 70-200 would be quite a exceptional little lens to always have on you.

Edit: While I am super excited about this, would be lovely to have a 200-500 f/5.6. The 70-200 range is covered by so many other lenses but getting past 400 is currently expensive or Nikon.

Is this a new way to differentiate offering from 3rd party providers - longer focal ranges at the same apertures.
Or is this because there won't be any APS-c RF mounts?

Great to see the 70-300 and 100-400 rolled into one lens, especially if it's a bit smaller than the EF 100-400L II. But - and I know it's been said a thousand times - it's *useless* without a body which performs for long lens subjects. And teleconverters, and extension tubes, and (please) an RF mount body with the 90D sensor.

There’s always the Sigma 150-600 option was well. But I agree; a 500 or 600 mm long end that doesn’t break the bank would be welcome.

If it weighs the same as the RF 70-200 that would really be amazing. The 100-400s have always been about as heavy as the 70-200 2.8s, and I'd love to see the same weight reduction achieved on the RF version of those on this RF 70-400!

The RF system gets more and more appealing when you are talking about weight savings. Nice lightweight f4s (ultrawide/70-200) would really round out a great a versatile zoom lens line-up from 15-400mm for the RF mount.

That's exciting! Though I wonder if they would have to make some optical compromises in order to get the size down. I thought I'd heard the 100-400 as it currently is, is one of Canon's toughest-to-make lenses, so I feel like miniaturizing that must come with a compromise or two...

But I could definitely see that in my bag should I jump on board with the R system any time soon.
